Document name Description Objective Product Specification (OPS) Applies to document versions up to 1.0. Product Specification (PS) This document contains target specifications for product development. Applies to document versions 1.0 and higher. This document contains final product specifications. Nordic Semiconductor ASA reserves the right to make changes at any time without notice in order to improve design and supply the best possible product. Table 1: Defined document names 2.2 Register tables Individual registers are described using register tables. These tables are built up of two sections. The first three colored rows describe the position and size of the different fields in the register. The following rows describe the fields in more detail. 2.2.1 Fields and values The Id (Field Id) row specifies the bits that belong to the different fields in the register. If a field has enumerated values, then every value will be identified with a unique value id in the Value Id column. A blank space means that the field is reserved and read as undefined, and it also must be written as 0 to secure forward compatibility. If a register is divided into more than one field, a unique field name is specified for each field in the Field column. The Value Id may be omitted in the single-bit bit fields when values can be substituted with a Boolean type enumerator range, e.g. true/false, disable(d)/enable(d), on/

off, and so on. Values are usually provided as decimal or hexadecimal. Hexadecimal values have a 0x prefix, decimal values have no prefix. The Value column can be populated in the following ways:

Individual enumerated values, for example 1, 3, 9. Range of values, e.g. [0..4], indicating all values from and including 0 and 4. Implicit values. If no values are indicated in the Value column, all bit combinations are supported, or alternatively the field's translation and limitations are described in the text instead. 4446_194 v1.0 6 About this document If two or more fields are closely related, the Value Id, Value, and Description may be omitted for all but the first field. Subsequent fields will indicate inheritance with '..'. A feature marked Deprecated should not be used for new designs. 2.2.2 Permissions Different fields in a register might have different access permissions enforced by hardware. The access permission for each register field is documented in the Access column in the following ways:

Access Description Hardware behavior RO WO RW W1 Read-only Write-only Read-write Write-once Field can only be read. A write will be ignored. Field can only be written. A read will return an undefined value. Field can be read and written multiple times. Field can only be written once per reset. Any subsequent write will be ignored. A read will return an undefined value. RW1 Read-write-once Field can be read multiple times, but only written once per reset. Any subsequent write will be ignored.

Device features include a configurable gain Power amplifier (PA) in the transmit path (TX) and a Low noise amplifier (LNA) in the receive path (RX). Single-ended operation on both TRX and ANT1/2 ports is supported and requires only three external components (for single antenna operation) for the RF path. The device is controlled through a set of input pins. Alternatively, the device can be controlled by writing to internal control registers through the SPI interface. The two antenna ports enable applications using antenna diversity and can be selected using pin ANT_SEL. Highly configurable gain in Transmit state enables the application to implement adaptive gain control algorithms. Gain settings can be stored for factory device calibration to user configurable output power through on-

board non-volatile memory. 4446_194 v1.0 8 4 Block diagram The block diagram illustrates the overall system.

The state machine can be controlled through direct pin control or through the built in SPI slave interface. 5.1 Operational states This section describes how nRF21540 can be set to different operational states. When PDN is set to 0, the device is in Power-down state. When PDN is set to 1, the device is activated and enters Program state. All registers will contain reset values when the device enters Program state. It can be set to any other state (Receive, Transmit, and UICR Program) using pin control or the SPI interface. State transitions are controlled by pins PDN, RX_EN, and TX_EN or bit fields in SPI registers CONFREG0 and CONFREG1. State transitions are shown in the following figure. For timings required when switching between operating states, see State transition timing on page 11. When the device is in Receive state, the receive path is active and the transmit path is disabled. In the Receive state, the LNA is enabled. When the device is in the Receive state, CSN needs to be driven low as shown in Figure 3: Pin control RX state on page 12. When the device is in Transmit state, the transmit path is enabled and the receive path is disabled. In Transmit state, the PA is enabled. The device features a configurable TX output power, see TX power control on page 13 for details. Note: Enabling multiple states simultaneously is not supported. UICR Program state enables programming of default settings for TX power control to UICR EFUSE (one time programmable memory). UICR Program state is accessed from Program state by writing specific values to register CONFREG1. Registers CONFREG2 and CONFREG3 are where bit programming definition and triggering of UICR EFUSE programming can take place. See UICR programming on page 13 for more details about UICR programming. The SPI register interface is described in detail in SPI interface on page 15. Receive Transmit RX_EN = 0 TX_EN = 1 RX_EN = 0 TX_EN = 0 RX_EN = 1 PDN = 1 TX_EN = 0 Program 1.

The device can be configured and set to other states. User defined initialization values for POUTA_SEL, POUTA_UICR, POUTB_SEL, and POUTB_UICR can be configured to UICR. Receive Transmit RX TX The RX path is enabled. CSN = 0 The TX path is enabled. Table 4: Operating states description 5.2 Antenna control ANT_SEL selects the antenna interface used during RX or TX. Antenna interface control is specified in the following table. State ANT_SEL Description Power-down Program UICR program Receive Transmit X X X 0 1 0 1 Antenna switches disabled (i.e. isolating) Antenna switches disabled (i.e. isolating) Antenna switches disabled (i.e. isolating) ANT1 enabled, ANT2 disabled ANT1 disabled, ANT2 enabled ANT1 enabled, ANT2 disabled ANT1 disabled, ANT2 enabled Table 5: Antenna switch control with ANT_SEL in different states 5.3 State transition timing Settling time requirements when switching between operational states are defined in the following table. When using SPI control, the maximum settling time is defined from the falling edge of SPI clock cycle 16. For more details on SPI, see SPI interface on page 15. Note: GPIO control is faster than SPI control. 4446_194 v1.0 11 Device control Symbol Parameter Note Max.

An example of RX timing using an RX_EN pin-based configuration is shown in the following figure. The following figure shows the Receive state configured using SPI. Figure 3: Pin control RX state The following figure shows the Transmit state configured through pin. Figure 4: SPI control RX state The following figure shows the Transmit state configured using SPI. Figure 5: Pin control TX state 4446_194 v1.0 12 Device control Figure 6: SPI control TX state 5.4 TX power control The output power for the Transmit state can be configured using either pin control or the SPI interface. Note: Gain should not be changed while the device is in the Transmit state. To configure the output power through pins, MODE can be used to set TX power control to one of two preset values. Preset values are used to update the TX_Gain value when MODE control changes in the Program state. The same functionality can be achieved by writing to the MODE bit in CONFREG0. Custom preset values can be stored in UICR and selected as default. The following table presents the TX_Gain initialization functionality. The SPI interface can also be used to control the output power. Before entering the Transmit state, TX Gain is configured by writing the gain value over SPI to register CONFREG0 TX_Gain field. SPI write will always overwrite the initialization value. The Gain word can be set in the same SPI write cycle as TX is enabled from the Program state. Changing MODE or the MODE bit in CONFREG0 will always trigger a reload of a default value to TX_Gain. Setting any of these will load POUTB. Clearing any of these will load POUTA. The default value will also be used even if a new value is loaded to TX_Gain during the SPI write cycle changing the MODE bit. The following table shows TX power control with MODE control and corresponding preset values of TX_Gain in program state.

Apply VDD supply voltage using the specifications set in the following table. Parameter VDD TOP Min. 3.45 V 0C Max. 3.60 V 85C Table 8: EFUSE programming conditions 2. Enable UICR Program state by writing Enable to field UICR_EN in register CONFREG1. 3. Enter UICR Program state by writing Enter to field KEY in register CONFREG1. 4. Write desired configuration values for POUTB_SEL and POUTB_UICR to register CONFREG3. 5. Write desired configuration values for POUTA_SEL and POUTA_UICR and write a 1 to WR_UICR in register CONFREG2. 6. Wait for 0.5 ms to guarantee successful programming. 7. Reset the circuit by setting PDN to 0 and then back to 1. The programmed values are now set for register CONFREG2 and CONFREG3. The device can be set to UICR mode to verify programmed values by reading registers CONFREG2 and CONFREG3. 4446_194 v1.0 14 6 SPI interface The data transitions for slave in and out (MOSI and MISO) happen on the falling edge of the serial clock

(SCK). All SPI transfers are two bytes long. Input data is sampled on the rising edge of SCK, starting with the first rising edge. Therefore, it is required that the first bit is stable on the first rising clock edge of SCK. Common definitions for SPI bus are CPOL = 0 and CPHA = 0. In other words, SPI mode 0. The serial data frame is 16 bits long and consists of three parts in the following transmission order: command (Cmd), address, and data. All fields are sent on MOSI line MSB first. In the event of a write operation, a command is 2 bits long, an address is 6 bits long, followed by 8 bits of data. CSN is active low and it is assumed that it is set to 0 at least half an SCK cycle before the first rising edge of SCK, and then again to logical 1 earliest after half a cycle of 16th SCK falling edge. The following commands are used:

READ, b10 This command allows reading of registers. The register address to read from is sent after the command. The read data will be clocked out to the MISO line during the data part of the SPI frame. WRITE, b11 This command allows writing to registers. The last 8 bits sent on the MOSI line will be written to a register pointed with 6-bit address field. The write command has writeback property. When a register is accessed by the write command to update its value, the previous register value will be written to MISO line in serial format MSB first. SPI timing specification presents the required timings between CSN signal and SCK edge. The following figure shows a configuration example for SPI when writing to register CONFREG0. The WRITE command b11 is written to the command field. The first bit on the MOSI line shall be set to its value (in this case to 1) before the first rising edge of SCK occurs, since Cmd is read on the rising edge of the first and second SCK cycle. SCK rising edges 3 to 8 are used to read the address field and 9 to 16 read the data field. Register CONFREG0 writeback data is written on the MISO line starting on the falling edge of cycle 8 so that cycle 9 to 16 rising edges can be used to read in MISO data on the Master side. Guaranteed settling time for the first read bit before the cycle 9 falling edge can be found in SPI timing specification. Functionality of the read operation is similar to writeback, meaning that read data is written to the MISO line starting on the cycle 8 falling edge when the read command is given in the Cmd field. An overview of register address space and accessibility of registers in different operation states is found in SPI timing. The detailed register map is given in the Register interface on page 20.

It is ideal for rapid development of prototypes for IoT systems. The Nordic Thingy:53 includes sensors that gather data about its own movements and the surrounding environment. Temperature, humidity, air quality, air pressure, color, audio, and light data can be easily extracted for local or remote analysis. For input, the Nordic Thingy:53 offers two user-programmable buttons. Visual output is achieved with an RGB indicator LED, while a buzzer can provide audible output. The preprogrammed firmware on the Nordic Thingy:53 allows to connect to the nRF Edge Impulse mobile application that can be used to sample training and test data from the Nordic Thingy:53 sensors. The sampled data can be used to train machine learning models in the Edge Impulse Studio. Trained machine learning models can be deployed to the Nordic Thingy:53 through Bluetooth Low Energy using the nRF Edge Impulse mobile application. The firmware has been developed using the nRF Connect Software Development Kit (SDK). The preprogrammed firmware on the Nordic Thingy:53 can be easily updated through Bluetooth Low Energy to other samples from the nRF Connect SDK using the nRF Programmer application for iOS and Android or through Universal Serial Bus (USB) using the nRF Connect Programmer. The firmware can be updated and debugged also by using an external programmer or debug probe, for example, the nRF5340 Development Kit (DK) or a J-Link device supporting Arm Cortex-M33. The Nordic Thingy:53 integrates the nRF5340 SoC which supports Bluetooth Low Energy, 802.15.4, and Near Field Communication (NFC) as a passive tag. The Nordic Thingy:53 integrates also the nRF21540 RF Front-End Module (FEM) for extended range and the nPM1100 Power Management Integrated Circuit

(PMIC) for power management and charging of the 1350 mA Li-Po battery. Source code for firmware, hardware layout, and schematics are available on the Nordic web site www.nordicsemi.com. The Nordic Thingy:53 has two 2.4 GHz antennas. One of them is connected to the nRF5340 SoC through an RF switch for TX output power up to +3 dBm. The other one is connected to the nRF21540 RF FEM with TX output power up to +20 dBm. NFC in the Nordic Thingy:53 operates as a passive tag which means that it does not feature a reader function. The Nordic Thingy:53 can use the tag function for the Out of Band (OOB) pairing feature as described in the Bluetooth Core Specification. Key features of Nordic Thingy:53 Two 2.4 GHz antennas and one NFC passive tag antenna RF FEM for increased range Insertable current measurement and debug board for easy power profiling and debugging Qwiic and STEMMA QT compatible connector for easy prototyping with breakout boards User-programmable buttons and RGB LED Environmental sensor for temperature, humidity, air quality, and air pressure Color and light sensor Low-power accelerometer 6-axis IMU with gyroscope and accelerometer Magnetometer Pulse Density Modulation (PDM) microphone with wake-on-sound functionality Buzzer 4471_002 5 Introduction 64 Mb external memory with Quad Serial Peripheral Interface (QSPI) interface Rechargeable Li-Po battery with 1350 mAh capacity Computer connection and battery charging through USB-C Normal operating temperature range 035C nRF5340 aQFN94 SoC Application core 12864 MHz Arm Cortex-M33 with TrustZone technology 1 MB flash and 512 kB low leakage RAM Arm TrustZone CryptoCell-312 security subsystem QSPI peripheral for communicating with an external flash memory device Execute-in-place with optional on-the-fly encryption and decryption NFC-A tag with wake-on field and touch-to-pair Up to five Serial Peripheral Interface (SPI) master/slave with EasyDMA Up to four Inter-integrated Circuit (I2C) compatible two-wire master/slave with EasyDMA Up to four Universal Asynchronous Receiver/Transmitter (UART) (Clear to Send (CTS)/Request to Send (RTS)) with EasyDMA Audio peripherals: I2C, digital microphone interface (PDM) Up to four Pulse Width Modulation (PWM) units with EasyDMA 12-bit, 200 ksps ADC with EasyDMA, eight configurable channels with programmable gain Full-speed (12 Mbps) USB device Network core 64 MHz Arm Cortex-M33 256 kB flash and 64 kB low leakage RAM Bluetooth 5.2, IEEE 802.15.4-2006, 2.4 GHz enabled transceiver SPI master/slave with EasyDMA I2C compatible two-wire master/slave with EasyDMA UART (CTS/RTS) with EasyDMA nRF21540 RF FEM FEM with RF Power Amplifier (PA) and Low-Noise Amplifier (LNA) Supports Bluetooth Low Energy, IEEE 802.15.4, and proprietary applications Output power 20 dBm at 3.0 V (maximum TX output power +22 dBm at 3.6 V) Adjustable output power to 1 dB from 5 to 21 dBm Receive gain +13 dB Control interface through I/O, SPI, or a combination of both nPM1100 PMIC 400 mA linear Li-ion/Li-Po battery charger with thermal protection Automatic trickle, constant current, and constant voltage charging Battery thermal protection Discharge current limitation 1.8 3.0 V, 150 mA step-down buck regulator Automatic transition between hysteretic and PWM modes Forced PWM mode for clean power operation Input regulator with USB compatible current limit of 100 mA and 500 mA 4471_002 6 4.16.7 V input voltage range for normal operation LED drivers for charger state indication 2.34.35 V battery operating input range Introduction WARNING: The battery in this product shall not be replaced by users themselves. Batteries should be removed only by qualified professionals due to the following safety concerns:

Replacing the battery with an incorrect battery type can cause a fire or explosion. Disposing the battery into a fire or hot oven, crushing it mechanically, or cutting it can cause an explosion. Leaving the battery in an environment with an extremely high temperature can cause an explosion or the leakage of flammable liquid or gas. Subjecting the battery to extremely low air pressure can cause an explosion or the leakage of flammable liquid or gas. The Nordic Thingy:53 shall not be operated outside the internal batterys discharge temperature range between 20C and +60C or stored or transported outside the internal batterys storage temperature range between 20C and +30C. 4471_002 7 2 Kit content The Nordic Thingy:53 kit consists of hardware and access to software components, hardware design files, applications, and documentation.

The two flexible processors combined with advanced security features and an operating temperature up to 105C make the nRF5340 SoC a great choice for professional lighting, advanced wearables, and other complex IoT applications. For more information on the nRF5340 SoC, see nRF5340 Product Specification. The following schematic describes the nRF5340 SoC. 4471_002 13 Hardware description Figure 7: nRF5340 SoC schematic 4.3.1 NFC The Nordic Thingy:53 supports the NFC antenna. The NFC-A Listen Mode operation is supported by the nRF5340 SoC. The NFC antenna input is available on connector J5. The following figure shows the NFC antenna connector on the Nordic Thingy:53. 4471_002 14 Hardware description Figure 8: NFC antenna connector NFC uses pins P0.02 and P0.03 to connect to the antenna. The pins can be used as regular General-

Purpose Input/Output (GPIO)s by changing their configurations. The PROTECT field in the NFCPINS register in UICR defines the usage of the pins and their protection level against abnormal voltages. The content of the NFCPINS register is reloaded at every reset. Note: The NFC pins are enabled by default. 4.3.2 USB The Nordic Thingy:53's USB connector (J6) is connected to the USB interface on the nRF5340 SoC and the nPM1100 PMIC. This enables the Nordic Thingy:53's communication with a computer and the charging of the battery. The following schematic describes the USB-C interface. Figure 9: USB-C interface 4471_002 15 Hardware description 4.3.3 Antenna selection The single-ended antenna output (ANT) of the nRF5340 SoC is connected to an RF switch (U17), which allows you to select either antenna A1 or antenna A2. The RF front end allows the nRF5340 SoC to transmit using only one antenna at a time, that is, A1 or A2. It is not possible to transmit with both antennas at the same time. The antenna selection is controlled through the SEL pin (P1.10). Antenna A1 is connected to the ANT1 port of the nRF21540 RF FEM, which is connected to the RF1 port of the RF switch. The nRF21540 RF FEM supports TX output power gain up to +20 dBm on the A1 antenna. The A2 antenna is connected directly to the RF2 port of the RF switch. The maximum TX output power supplied to A2 is +3 dBm. The following table shows antenna gain over frequency for the A1 and A2 antennas. Antenna A1 A2 2402 MHz

-0.20 dBi Table 1: Antenna gain for A1 and A2 Note: The RF switch adds approximately 0.5 dB insertion loss. The OR gate (U16) is not mounted. The following schematic describes the antenna selection. Figure 10: Antenna selection 4.3.4 RF measurements The 2.4 GHz signals can be propagated through the coaxial connectors J1 and J2. The connectors allow you to perform conducted measurements or to attach external antennas. When an adapter cable is not connected, the RF signal is routed to the onboard antenna. When an adapter cable is connected, the internal switch in the SWF connector disconnects the onboard antenna and connects the RF signal from the nRF5340 SoC or nR21540 RF FEM to the adapter. You can use a Murata adapter cable (part no. MXHS83QE3000) with a standard SMA connection on the other end for connecting instruments. The adapter is not included in the kit. The insertion loss in the adapter cable is approximately 0.51 dB. 4471_002 16 Hardware description 4.4 nRF21540 RF FEM The Nordic Thingy:53 uses the nRF21540 RF FEM (U2) to improve the range and robustness of the connection on the nRF5340 SoC. The nRF21540 RF FEM enables RX gain up to +13 dB, low noise figure of 2.5 dB, and TX output power up to +21 dBm. Note: The ANT2 port of nRF21540 RF FEM is terminated to 50 as recommended in the nRF21540 RF FEM reference circuitry for single antenna. The ANT_SEL pin of the nRF21540 RF FEM is therefore connected to ground. The nRF21540 RF FEM can be controlled through direct pin control or a built-in SPI slave interface. You can select a predefined output level of +10 dBm or +20 dBm with direct pin control using the P0.12 GPIO that is connected to the nRF21540 RF FEM MODE pin. To set an output power level that is not predefined you must use the SPI. For more information on the TX power control on the nRF21540 RF FEM, see TX power control in nRF21540 Product Specification. 4.5 Pin maps The pin assignments for the nRF5340 SoC are listed in the pin map table.

When the Nordic Thingy:53 is in low-power sleep mode, any user interaction is detected by the low-power accelerometer. The accelerometer can be used to generate a GPIO interrupt that wakes up the device. It has an SPI, and it can detect motion on three axes. Note: Only the ADXL_INT1 pin is connected to the nRF5340 SoC. The following schematic describes the low-power accelerometer. Figure 11: Low-power accelerometer The 6-axis IMU has an SPI, and it can be used for more advanced motion sensing applications. The IMU can generate a GPIO interrupt when sensor data is ready. Note: Only the BMI270_INT1 pin is connected to the nRF5340 SoC. The following schematic describes the IMU. Figure 12: IMU The magnetometer can be used to detect magnetic fields around the Nordic Thingy:53. It can be used as a standalone device or with the 6-axis IMU. The magnetometer has an I2C interface, and it can generate a GPIO interrupt when magnetometer sensor data is ready. Note: Only the BMM150_INT1 pin is connected to the nRF5340 SoC. 4471_002 19 Hardware description The magnetometer can be connected to the auxiliary I2C bus of the 6-axis IMU to ensure that the data sampling is synchronized. This means that the magnetometer data is sampled at the same time as the accelerometer and gyroscope data. This can be important especially for sensor fusion applications. To connect the magnetometer to the auxiliary I2C bus of the IMU, you must cut SB1 and SB2 and solder SB3 and SB4. The following schematic describes the magnetometer. Figure 13: Magnetometer 4.7 Environmental sensors The multisensor device (U9) on the Nordic Thingy:53 contains sensors for temperature, humidity, air quality, and air pressure. The multisensor device is connected to the I2C bus. The following schematic describes the environmental sensors. Figure 14: Environmental sensors The color sensor (U10) on the Nordic Thingy:53 senses red, green, and blue light. The sensor is located under the RGB LED light guide to direct the light to the sensor. The color sensor is accessed through I2C. The following schematic describes the color sensor. Figure 15: Color sensor 4471_002 20 Hardware description 4.8 Microphone and buzzer The PDM microphone (U13) on the Nordic Thingy:53 captures audio input. The PDM microphone has also a Wake-on-Sound feature that can be used to wake up the nRF5340 SoC when an audio event exceeds a set threshold. In an audio event, the DOUT pin (P0.25) is pulled high. The nRF5340 SoC can use the interrupt to start the PDM clock and sample audio data. The following schematic describes the PDM microphone. Figure 16: PDM microphone For audio output, the Nordic Thingy:53 has a piezo buzzer (BZ1). The buzzer is driven by a transistor using the PWM input. The following schematic describes the buzzer. Figure 17: Buzzer 4.9 External memory The Nordic Thingy:53 has a 64 Mb external flash memory (U15). The memory is a multi-I/O memory supporting regular SPI and QSPI. The following schematic describes the external memory. Figure 18: External memory 4471_002 21 Hardware description Note: Only QSPI0 and QSPI1 are connected to the nRF5340 SoC. 4.10 LEDs and buttons The user interface on the Nordic Thingy:53 consists of an RGB LED and two buttons. 4.10.1 RGB LED The Nordic Thingy:53 is equipped with a single RGB LED (LD1) that is controlled by three signals from the nRF5340 SoC that are connected to transistors acting as switches. The RGB LED provides visual feedback to the user. It can be used also as an auxiliary light for color measurements. The following schematic describes the RGB LED. Figure 19: RGB LED 4.10.2 Buttons The Nordic Thingy:53 has two buttons that are connected to the nRF5340 SoC. The main button (SW3) is located under the circle on the top part of the casing and used for user input. The other button (SW2) can also be used for user input, but it can be accessed only by removing the top part of the casing. You can activate serial recovery mode by pressing and holding SW2 when power-cycling the device. The following schematic describes the buttons. 4471_002 22 Hardware description The following figure shows the buttons on the Nordic Thingy:53. Figure 20: Buttons Figure 21: Nordic Thingy:53 buttons 4.11 Power supply The main power source on the Nordic Thingy:53 is a rechargeable Li-Po battery. The battery has a nominal capacity of 1350 mAh and can be recharged through USB. The Li-Po battery is connected directly to the nPM1100 PMIC (U3), which ensures that the Nordic Thingy:53 is charged regardless of the position of the power switch (SW1). In the ON position, the nPM1100 PMIC supplies power to the rest of the Nordic Thingy:53 board through its VSYS and VOUTB voltage domains. When the power switch is in the OFF position, the two voltage domains of the nPM1100 PMIC are disconnected. With the power switch in the OFF position, a circuit drains the voltage charge across the capacitors that are connected to the VOUTB power domain. The following schematic describes the power switch. 4471_002 23 Hardware description Figure 22: Power switch 4.11.1 nPM1100 PMIC The Nordic Thingy:53 uses the nPM1100 PMIC (U3) for power management and battery charging. The nPM1100 PMIC has two voltage domain outputs:

Unregulated VSYS output (3.24.2 V) VOUTB output (3.0 V) The unregulated VSYS output is used to supply the external 3V3 regulator and the buzzer (BZ1). The 3V3 regulator supplies the RGB LED (LD1) and any external boards connected to the expansion board connector (P1). The VOUTB domain is configured to 3.0 V and used to supply the nRF5340 SoC, the nRF21540 RF FEM, and all the sensors. The VOUTB output is configured to 3.0 V by connecting VOUTBSET0 and VOUTBSET1 to the DEC pin (A3) (see Output voltage selection (VOUTBSET0, VOUTBSET1) in nPM1100 Product Specification). The following schematic describes the nPM1100 PMIC. Figure 23: nPM1100 PMIC The current limit of the nPM1100 PMIC's battery charger is set to 400 mA, but the actual charging current depends on the VBUS current limit. The nPM1100 PMIC detects automatically if it is connected to a 4471_002 24 Standard Downstream Port (SDP), Dedicated Charging Port (DCP), or Charging Downstream Port (CDP) USB port and sets the VBUS current limit according to the USB port type. The following table describes the VBUS current limits for the different USB port types. Hardware description USB port type VBUS current limit SDP DCP CDP 100 mA 500 mA Table 3: VBUS charging limits for different USB port types The nRF5340 SoC can negotiate a 500 mA limit with the USB host if the USB host supports this. If the 500 mA limit is negotiated, the nRF5340 SoC can set the ISET pin on the nPM1100 PMIC high to set the VBUS current limit to 500 mA. Note: The ISET pin must be set to LOW on reset and whenever USB is disconnected. ISET should be set to HIGH only when the USB port type is SDP and negotiation for a higher current limit is completed. The nPM1100 PMIC has a charging indication pin CHG and charging error indication pin ERR that signal the charger status to the nRF5340 SoC. The CHG pin is connected to GPIO P1.00, and the ERR pin is connected to GPIO P1.01. P1.00 and P1.01 have pull-ups enabled. When the nPM1100 PMIC is charging the battery, the CHG pin is pulled low. When a charging error occurs, the ERR pin is pulled low. The buck regulator on the nPM1100 PMIC can operate in two modes: in hysteretic mode for low load currents and in PWM mode for high load currents. The nPM1100 PMIC switches automatically between the two modes based on the load. For the load threshold values, see nPM1100 Product Specification. In some cases, such as in high-accuracy ADC measurement, it can be beneficial to force the nPM1100 PMIC to operate in PWM mode. This is done by pulling the MODE pin on the nPM1100 PMIC high by using the TRACEDATA3 (P0.08) pin that is routed to the current measurement and debug interface connector

(P9). The nPM1100 PMIC MODE pin is connected to P0.08 and pulled to ground through R7. The following schematic describes the nPM1100 PMIC status and control. Figure 24: nPM1100 PMIC status and control 4.11.2 Battery voltage monitor The Nordic Thingy:53 has a battery monitoring circuit which allows the battery voltage to be sampled by the nRF5340 SoC ADC. 4471_002 25 Hardware description Transistors Q7A and Q7B enable battery voltage sensing through a resistive divider (R11 and R15). When not sampling, the transistors can be turned off with the BAT_MEAS_ENABLE (P0.16) signal to prevent current leakage to ground. The circuit is designed to ensure that the voltage range on the BAT_MEAS pin over the battery voltage is within the limits required by the nRF5340 SoC GPIO and ADC. When sampling, the battery voltage of 2.84.2 V is scaled down to 360540 mV at BAT_MEAS (P0.06). The following schematic describes the battery voltage monitor. Figure 25: Battery voltage monitor 4.11.3 External 3.3 V regulator The Nordic Thingy:53 can power external devices with up to 300 mA through a 3.3 V regulator (U6) that is connected to the nPM1100 PMIC's VSYS output. The VSYS output is exposed also on the current measurement and debug connector (P6). When the 3.3 V regulator is not in use, it can be turned off by pulling the 3V3_ENABLE pin (P0.15) low. Note: In the Nordic Thingy:53 board files in Zephyr, 3V3_ENABLE is set low by default. The following schematic describes the regulator. Figure 26: Regulator 4.11.4 Sensor power control The sensors on the Nordic Thingy:53 can be powered down through a load switch (U19) which is connected to P0.31 on the nRF5340 SoC. Note: In the Nordic Thingy:53 boards files, the SENS_PWR_CTRL pin (P0.31) is pulled high by default. 4471_002 26 The following schematic describes the sensor power control circuit. Hardware description Figure 27: Sensor power control circuit 4.11.5 Current measurement You can use the Nordic Thingy:53 current measurement and debug board to measure certain currents on the Nordic Thingy:53. The currents are the following:

The current flowing to the nPM1100 PMIC from the battery through the P1 connector The current flowing to the nRF5340 SoC from the VOUTB rail through the P2 connector The current flowing to the nRF21540 RF FEM from the VOUTB rail through the P3 connector The current flowing to external devices from the 3V3 regulator through the P4 connector Load switches U4, U5, U11, and U14 are disengaged when the Nordic Thingy:53 current measurement and debug board is inserted into the debug board interface (P9). The following schematic describes the load switches. 4471_002 27 Hardware description Figure 28: Load switches 4.12 Programming and debugging interface The Nordic Thingy:53 has a programming and debugging interface connector (P8). The programming and debugging interface is available also on the current measurement and debug interface connector (P9). The following schematic describes the SWD Interface. Figure 29: SWD Interface 4471_002 28 Hardware description 4.13 Interfaces Some of the GPIOs on the nRF5340 SoC are routed to test points for test purposes or to connectors to enable to connect to external hardware. The following sections describe these connectors and test points. CAUTION: The trace functionality through the current measurement and debug board, Serial Wire Debug (SWD) interface, and expansion board interface (4-pin JST connector) are disabled by software in the factory-programmed firmware. These features can be enabled by custom firmware, but such modification may void the FCC authorization of the device. See Regulatory notices on page 36. 4.13.1 Current measurement and debug interface The Nordic Thingy:53 kit comes with a current measurement and debug board that can be inserted into the P9 connector on the Nordic Thingy:53. The current measurement and debug board simplifies the current consumption measurement of the four different power domains with a power profiling tool, such as the Power Profiler Kit II. The interface also enables a trace debugging functionality and the possibility to connect external circuits or boards to the Nordic Thingy:53 by using the TRACE pins as regular GPIOs. The pins are configured as GPIOs by default. Its recommended to connect external loads to VOUTB or 3V3. The maximum load on VOUTB is 150 mA. The maximum allowed current drawn by external circuitry on VOUTB depends on the total internal current draw. The maximum load on the 3V3 rail is 300 mA. The following schematic describes the current measurement and debug interface.

Connector P1 is compatible also with the STEMMA, Grove, and DFRobot Gravity prototyping systems, but they require a cable to convert from a 1 mm pitch connector to a 2 mm pitch connector. The following schematic describes the expansion board interface. 4471_002 30 Hardware description Figure 31: Expansion board interface 4.13.3 Connectors The Li-Po, 3 V, and 3V3 power domains are available on connectors P3P5 on the Nordic Thingy:53 PCB.
