Operation Casambi CBM-003 is an embedded wireless module with a powerful 32-bit ARM Cortex -M4 CPU and a 2.4 GHz transceiver with an onboard antenna. It can be integrated, for example, into an LED driver, a light fixture, LED bulb, or any sensor. The CBM-003 has a total of 12 GPIO pins, which can be configured to perform various tasks, such as SPI, TWI (I2C compatible), UART, 8 PWM outputs, and 4 channel Analog-to-Digital Converter input. ADC input channels have fixed GPIO pins. Other functions can be configured to any free GPIO pin. Note: The CBM-003 is based on nRF52840 chip, which has some limitations compared to earlier models. Many of nRF52840 pins are recommended to be used only in standard-drive (2 mA) and low-frequency (10kHz) mode. CBM-003 has 6 standard and 6 High-drive GPIOs. 2. Block Diagram All >10KHz and High-drive IOs shall be connected to High-drive pins, otherwise radio performance may be compromised. The CBM-003 has an integrated 2.4 GHz antenna, so this will have to be considered when the device is integrated into any environment. See chapter 7 for further instructions. Many of the CBM-003's different settings can be configured in the Casambi Admin webtool and taken into use without the need of re-programming the module. These settings include, for example, I/O pin mapping, PWM, and push-buttons. The Casambi CBM-003 is based on the Nordic Semiconductor nRF52840 chip, and all technical data shall be referred to regarding the chip's datasheet. CBM-003 block diagram casambi.com 3 3. System blocks 3.1 General Purpose I/O (GPIO) The CBM-003 has 12 General Purpose I/O pins. Some of them are High-drive (9 mA) while some are standard-drive (2 mA). Each GPIO can be accessed individually, and each has the following features:
Input/output direction Configurable output drive strength, standard-drive (6 pcs) or High-drive (6 pcs) Configurable internal pull-up and pull-down resistors Buffered inputs Trigger interrupt on all pins (rising edge, falling edge, any change) Serial interface output can be freely configured to any of 6 High-drive pins
>10 kHz PWM output can be freely configured to any of 6 High-drive pins 10 kHz PWM output can be freely configured to any of 12 GPIO pins GPIO pins 0-3 also support analog input signals when an internal Analog-to-Digital Converter (ADC) is used. 3.2 Analog-to-Digital Converter (ADC) The Casambi system can use an Analog-to-Digital Converter (ADC), for example, in light level sensing and battery voltage monitoring. The ADC resolution is selected automatically (8-bit or 12-bit) based on the application. The specific functionality available through the ADC inputs is determined by Casambi Firmware and how it is configured. CBM-003 The Analog-to-Digital Voltage range for any ADC input is 0-3.6 V, but not above Vcc. This means that 0 V gives a zero reading from the ADC, and 3.6 V gives a maximum reading (255 for 8-bit and 4095 for 12-bit resolution). No pin should be exposed to voltages higher than VCC. The operating voltage of the module, VCC, is the maximum limit to the analog input voltage. While the full range of ADC is 3.6V, if the supply voltage Vcc is only 3.3V or 3.0V, the full range cannot be used. 3.3 PWM Output Any GPIO pin can be configured to output a PWM signal, and up to 8 PWM channels can be used simultaneously. A PWM frequency can be determined freely up to 40 kHz and is the same with all PWM channels. However, any PWM over 10 kHz requires the use of High-drive pin. The resolution can be selected between 100-5000 steps. The maximum resolution depends on the PWM frequency. The PWM signal is logic level (max. VCC), and it has a driving capacity of 2 mA (standard) or 9 mA on a High-drive pin. See also the Nordic nRF52840 datasheet for limitations. An adjustable analog voltage
(0 V - VCC) can be derived from the PWM signal by an external RC filter. Picture 2 Adjustable 010V output from PWM signal casambi.com 4 4. Serial Interfaces The CBM-003 can be connected to an external MCU through its Casambi proprietary interface extension interface, which supports SPI, TWI, and UART. All extension interface signals shall be connected to High-drive pins if data rate exceeds 10 kHz. UART/SPI/
TWI interfaces are dedicated for this purpose and are not available for generic use outside of Extension Interface Protocol without special arrangements from Casambi Technologies. Through this interface, it is possible to, for example, gather information from sensors within the Casambi network. For detailed serial info, refer to the nRF52840 datasheet. For detailed Casambi extension interface, refer to the Firmware Extension Interface datasheet. 4.1 Serial Peripheral Interface (SPI) The CBM-003 supports a 4-wire (SCK, MISO, MOSI, SS) bidirectional SPI bus with fast data transfers to connected MCU ('client'). The SPI peripheral supports SPI modes 0 through 3. 4.2 Two-Wire Interface (TWI) The Two-Wire Interface (I2C compatible) can interface a bidirectional wired-AND bus with two lines (SCL, SDA). The interface is capable of clock stretching, and data rates of 100 kbps and 400 kbps are supported. The TWI transmitter and receiver are single buffered. 4.3 Universal Asynchronous Receiver/Transmitter (UART) The Universal Asynchronous Receiver/Transmitter offers fast, full-duplex, asynchronous serial communication with built-in flow control support in HW up to 1 Mbps. Parity checking and generation for the 9th data bit are supported. 5. Pin Assignment Top side Bottom side from above Bottom side TOP PINS BOTTOM PINS BOTTOM PINS casambi.com 5

Module installation placement The CBM-003A uses an antenna that operates best when the CBM-003A module is properly grounded on the carrier PCB ground plane and has three extra grounding terminals for this purpose. However, the module can be used without connecting these terminals, but it may decrease antenna performance. The antenna side ("A") is located at the edge of the carrier board. The CBM-003 antenna is not affected by surrounding materials. However, it's always good to avoid having nearby plastic or metal objects within its vicinity.
