This hybrid approach ensures both excellent short-term linearity and long-term accuracy. Furthermore, neither full battery charge cycling, nor zero-current-load conditions, are required to maintain the accuracy. The fuel gauge measures the battery pack temperature by sensing the voltage across an external thermistor. Missing battery detection is also incorporated to accurately monitor battery insertion and removal scenarios, while properly updating the state of charge when a battery is reconnected. Using precise measurements of battery voltage, current, and temperature, the fuel gauging algorithm compensates for the variation in battery characteristics across temperature changes and aging effects.

All rights reserved. 6 Robotics RB5 Development Kit Hardware User Manual Block diagram part #2 Copyright 2020 Thundercomm Technology Co., Ltd. All rights reserved. 7 Robotics RB5 Development Kit Hardware User Manual 3.2 Processor QRB5165 is the new generation Qualcomm Snapdragon premium-tier processor with robotic application. It is designed with the 7 nm process, for superior performance and power efficiency. 3.3 Memory The QRB5165 uses a package on package (PoP) LPDDR5 RAM configuration and discrete UFS3.0 flash memory. The LPDDR5 interface goes directly to the QRB5165 built-in LPDDR controller. The maximum DDR clock is 2750MHz. The UFS flash memory interfaces with QRB5165 over a dedicated UFS PHY bus supporting the UFS 3.0 specification. 3.4 MicroSD MicroSD slot signals are routed directly to the QRB5165 SDC2 interface. Copyright 2020 Thundercomm Technology Co., Ltd. All rights reserved. 8 Robotics RB5 Development Kit Hardware User Manual The slot is a push-push type with dedicated support for card detect signal (many microSD slots do not have dedicated CD pins, they use DATA3 state as the card detected signal). RB5 uses AP GPIO_77 as the SD_CARD_DET_N. 3.5 Wi-Fi/BT RB5 uses the Qualcomm RF chip QCA6391 solution that integrates two wireless connectivity technologies into a single device. The interfaces are:

WLAN-compliant with IEEE 802.11 b/g/n/ac/ax specifications, exceeding 96Boards minimum Wi-Fi requirements Bluetooth compliant with BT Milan and ANT+, supports BLE/BLE long range(BT specification version 5.1), meeting the 96Boards BT requirements The antenna socket #27, for Wi-Fi chain 0 (and optionally BT) and antenna socket #24, for Wi-Fi chain1 are just backup solutions. 3.6 Display Interface 3.6.1 HDMI The 96Boards specification calls for an HDMI port to be present on the board. Because QRB5165 doesn't include a built-in HDMI interface, RB5 deploys the built-in MIPI-DSI 2x4 lanes interface as the source for the HDMI output. A DSI to HDMI Bridge

(LONTIUM SEMICONDUCTOR LT9611UXC) performs this task and it supports a resolution from 1080p to 4K at 60Hz. While the LT9611UXC supports automatic input video format timing detection (D-PHY1.2, DSI1.3/CSI-2 1.00 and DCS 1.02.00), an I2C channel from the QRB5165 also allows users to configure the operation of this bridge. It is QUP5 I2C interface from SoC. This bridge supports audio as well (meeting the 96Boards requirements for providing audio via HDMI). The RB5 uses a 4 bit I2S2 interface from the QRB5165 for this task. Copyright 2020 Thundercomm Technology Co., Ltd. All rights reserved. 9 Robotics RB5 Development Kit Hardware User Manual 96Boards specification also calls for a MIPI-DSI interface to be routed to the High Speed Expansion connector. Since the QRB5165 has two MIPI-DSI interface for HDMI, two multiplexing devices (FSA644UCX) are used. Only one interface, HDMI, or the Expansion MIPI-DSI can be active at one time. Control signal,DIP_HDMI_SWITCH, comes from DIP switch#16. When this signal is set to OFF state, DIP_HDMI_SWITCH is logic HIGH1, MIPI-DSI signals will be routed to DSI-HDMI Bridge. When the signal of DIP switch is set to ON state, DIP_HDMI_SWITCH as logic LOW0, MIPI-DSI signals will be routed to the High Speed Expansion connector. 3.6.2 MIPI-DSI RB5 has 2x 4-lane MIPI_DSI interface. See below for details. 3.7 Camera Interfaces RB5 has 6x 4L camera interfaces. 4-lane CSI0 camera on high-speed connector HS1 (section1.2.1 #6) ;

4-lane CSI1camera on high-speed connector HS2 (section1.2. #13) 4-lane CSI2 camera on high-speed connector HS2 (section1.2.1 #13) 4-lane CSI3 camera on high-speed connector HS1 (section1.2.1 #6) and high-speed connector (section1.2.1 #7) 4-lane CSI4 camera on high-speed connector HS3 (section1.2.1 #7) 4-lane CSI5 camera on high-speed connector HS3 (section1.2.1 #7) 3.8 USB Ports Copyright 2020 Thundercomm Technology Co., Ltd. All rights reserved. 10 Robotics RB5 Development Kit Hardware User Manual 3.8.1 USB-Host ports The QRB5165 processor includes two USB channels:

USB0 (section1.2.1 #5) is for USB Type C. USB1 (through a USB HUB to section1.2.1 #1&#3) is USB host only ports. RB5 supports below USB host ports by USB HUB mentioned above:

Two Type A USB Host 3.0 (super-speed) connector, each with current limit 1.2A. USB 3.0 signals are also routed to high-speed expansion connector HS1&HS2. 3.8.2 USB TypeC port RB5 implements a USB Type C port (section1.2.1#5) This Type C port supports both device and host mode with different peripherals. The board can work in one mode at a time. NOTE: There is a micro USB port section1.2.2#21. This micro B USB port is used only for debug-log-output from the QRB5165 with a debug UART to USB bridge. 3.9 Audio The 96Boards specifications calls for a minimum of single channel audio through two interfaces, BT and HDMI/MHL/DisplayPort. RB5 meets this requirement with HDMI, Display Port, and other audio channels. Note that MHL is not supported. 3.9.1 BT Audio The BT 5.1 implementation (including audio) on the Qualcomm Robotics RB5 Development Kit is with QRB5165 and QCA6391. 3.9.2 HDMI Audio A 4-bit (audio out only) I2S channel is routed directly from the QRB5165 SoC I2S interface pins to the DSI-HDMI bridge. 3.9.3 DisplayPort Audio The DisplayPort audio is routed directly from the QRB5165 SoC eDP interface pins to the Type C USB connector. Copyright 2020 Thundercomm Technology Co., Ltd. All rights reserved. 11 Robotics RB5 Development Kit Hardware User Manual 3.10 DC-power and Battery Power RB5 power is supplied in one of the following ways:

8 V to 18 V power from a dedicated DC jack 8 V to 18 V power from the DC12V pins on the low-speed expansion connector See Section 6 for details on Robotics RB5 Development Kit DC power implementation. 3.11 DC power Measurements The 96Boards specification calls for support for measuring board power consumption. See Section 6 for details on Robotics RB5 Development Kit DC power measurement. 3.12 Buttons The 96Boards specification calls for the presence of two buttons, a power on/sleep button and a reset button. RB5 meets these requirements. See Section 7 for details on RB5 buttons. 3.13 External Fan connection The 96Boards specification calls for support of an external fan. There is a on-board fan connector on main IO(see section 1.2.2, #25), fan power is 12V. 3.14 UART RB5 supports one 4bit UART, and a 2bit UART (optional), and both of them are routed to the low-speed expansion connector. The 4bit UART comes directly from SoC pins to low-speed expansion connector. The 2bit UART is optional an on-board UART debug log port via Micro USB port#21, or to be routed to low-speed expansion connector. To use the port for log output, switch DIP_DEBUG_UART_SWITCH on DIP switch (section 1.2.2#16) to ON. 3.15 JTAG (NA) NA 3.16 System and user LEDs RB5 supports seven LEDs on the board. LEDs color and mechanical location on the board are designed based on 96Boards specification. Two activity LEDs Copyright 2020 Thundercomm Technology Co., Ltd.

RB5 implements a full SPI master with 4 wires: CLK, CS, MOSI, and MISO. All signals go directly to the QRB5165 SoC. These signals are driven at 1.8 V. 4.1.5 PCM/I2S The 96Boards specification calls for one PCM/I2S bus to be provided on the low-speed expansion connector. The CLK, FS, and DO signals are required while the DI is optional. RB5 implements a PCM/I2S with 4 wires: CLK, FS, D0~D1. The I2S signals are connected directly to the QRB5165 SoC. These signals are driven at 1.8 V. 4.1.6 Power and Reset The 96Boards specification calls for a signal on the low-speed expansion connector that can power on/off the board and a signal that serves as a board reset signal. RB5 routes the PWR_BTN_N signal to the KYP_DPWR_N pin of the PM8250 PMIC. This signal is available on the onboard Power ON button switch (see Section 1.2.2, #20). The button only provides an ON/Sleep function and not OFF functionality. A mezzanine implementation of this signal should not drive it with any voltage, the only allowed operation is to force it to GND to start the board from a sleep mode. A board shutdown will occur when this signal is held to ground for more than 15 seconds. RB5 routes the RST_BTN_N (named PM_RESIN_N on the Robotics RB5 Development Kit schematic) signal to the RESIN_N pin of the PM8250 PMIC. This signal is driven by SW1302, the onboard reset switch (see Section 1.2.2, #17). This signal is dual purpose, the default purpose is Volume down, and the second purpose is the Reset function which needs the software configure setting.

A minimum of one lane is required and up to four lanes can be accommodated on the connector. RB5 implementation supports a full 4-lane MIPI-DSI interface that is routed to HS1. A DSI switch, FS644, is used to support on board DSI-to-HDMI bridging. DSI switch is controlled via DIP switch #16, pin4, DIP_HDMI_SWITCH. When set to ON, it will enable DSI0 to HS1 and DSI1 to HS3; when set to OFF, will enable DSI1&2 to LT9611UXC and on board HDMI. 5.1.2 MIPI CSI The 96Boards specification calls for two MIPI-CSI interfaces to be present on the high-

speed expansion connector. Both interfaces are optional. CSI0 interface can be up to four lanes while CSI1 is up to two lanes. The current Robotics RB5 Development Kit implementation supports a full 4-lane MIPI-

CSI interface on CSI0 and two lanes of MIPI-CSI on CSI3. All MIPI-CSI signals are routed directly to and from the QRB5165 processor. 5.1.3 I2C The 96Boards specification calls for two I2C interfaces to be present on the high-speed expansion connector. Both interfaces are optional unless a MIPI-CSI interface has been implemented. In this case, an I2C interface shall be implemented.

RB5 uses five buck regulators: U0700, U0701, U0800, U0801 as the main power suppliers for RB5, provide 4.2V for 865 SOM, 4.2V, 5V and 3.3V for peripherals in RB5. U0700 and U0701 generate 4.2 V at 4A. U0700 feeds the 4.2V power for peripherals in RB5. U0701 feeds the 865 SOM power. U0800 generates 3.3 V at 4A. U0801 generates 5 V at 4A. 6.1 DC Power Input The 96Boards specification calls for power to be provided to the board in one of the following ways:

8 V to 18 V power from a dedicated DC jack RB5 supports this requirement through the use of #15 (see Section 1.2.1). 8 V to 18 V power from the DC12V pins on the low-speed expansion connector llA USB Type C port at 5 V The Robotics RB5 Development Kit supports the 5 V from USB Type C port. It cannot support system bring up power on. 6.2 Power Source Selection The 96Boards specification calls for only one power source to be applied to the board at any given time. Following this requirement, RB5 user should never apply power to the board from #15

(see Section 1.2.1) and the low-speed expansion connector at the same time. There is no active or passive mechanism on RB5 to prioritize one source over the other. 6.3 Power Sequencing Upon applying power to the DC12V of Robotics RB5 Development Kit (from either one of the two sources), some power will be automatically enable, some will waiting S/W to enable. 4.2V for 865 SOM: will enable after DC12V is asserted. 865 SOM will power on once Copyright 2020 Thundercomm Technology Co., Ltd. All rights reserved. 35 Robotics RB5 Development Kit Hardware User Manual power-on button is pressed. 4.2V for IO peripheral: will not enable, S/W can enable it after 865 SOM is powered on. 3.3V/5V for IO peripheral: same as 4.2V for IO peripheral. These 3 power rails are controlled via one same signal. 6.4 Power Measurements The 96Boards specification calls for a minimum of one current sense resistor to be placed on the board permitting basic power measurement functions. RB5 implements two different power measurements. 6.4.1 DC-In measurement A 0.01ohm resistor R0700 is placed in line of the DC12V on the DC input. Placing a probe over the resistor pins will provide a voltage measurement of the voltage drop across the resistor. Dividing this measurement by 0.01 will give you the amount of the current flowing into the DC. 6.4.2 PMIC Power-In measurement (VPH_PWR measurement) A 0.01ohm resistors are used on output path of these two 4.2V, 3.3V and 5V for current measurement, i.e. R0709 for 4.2V of SOM, R0703 for 4.2 V of IO, R0801 for 3.3V of IO and R0805 for 5V of IO. Placing a probe over the resistor pins will provide a voltage measurement of the voltage drop across the resistor. Dividing this measurement by 0.01 will give you the amount of the current.

This hybrid approach ensures both excellent short-term linearity and long-term accuracy. Furthermore, neither full battery charge cycling, nor zero-current-load conditions, are required to maintain the accuracy. The fuel gauge measures the battery pack temperature by sensing the voltage across an external thermistor. Missing battery detection is also incorporated to accurately monitor battery insertion and removal scenarios, while properly updating the state of charge when a battery is reconnected. Using precise measurements of battery voltage, current, and temperature, the fuel gauging algorithm Copyright 2018 All Rights Reserved, Thundercomm Technology Co., Ltd. 4 Thundercomm TurboX C865 System on Module compensates for the variation in battery characteristics across temperature changes and aging effects. This provides a dependable state of charge estimate throughout the entire life of the battery and across a broad range of operating conditions.
