RAKwireless WisTrio NB-IoT Tracker Pro RAK5010/BG95-M3 Module Kit

The RAK5010 is typically programmed using the RUI3 (RAKwireless Unified Interface) API within the Arduino IDE. You can install the RAKwireless Arduino BSP, select the RAK5010 board, and develop applications in C/C++ to manage cellular connectivity, BLE, and sensor data. The RUI3 abstraction layer simplifies AT command handling for the BG95-M3 modem and BLE stack configuration.

The module operates from a 3.7V to 5V input, commonly supplied by a 3.7V Li-ion battery. Current consumption varies by mode: peak transmit currents can reach ~300mA during cellular transmission, while deep sleep with BLE and cellular radios disabled can draw as low as 5-10µA. For long battery life, design your firmware to maximize time in PSM (Power Saving Mode) of the BG95 module.

Network mode is configured via standard AT commands sent over the primary UART interface. Use AT+QCFG="nwscanmode" to set preference for CAT-M, NB-IoT, or both. You must also configure the APN for your cellular provider. The RUI3 framework provides wrapper functions (e.g., api.cellular.attach()) to handle these commands, simplifying the network registration and data connection process.

No, the BG95-M3 modem supports a single active SIM profile at a time. You can physically install a nano-SIM or use the integrated eSIM, but they cannot be active concurrently. Switching between them requires a power cycle and reconfiguration via AT commands (AT+QCFG="ims" for eSIM selection). The eSIM is managed remotely by your IoT connectivity platform for OTA profile provisioning.

The board exposes several interfaces: a primary UART for debug/AT commands, a secondary UART, an I2C port for sensors like accelerometers or environmental chips, multiple GPIOs for digital input/output, and ADC pins for analog sensing. The specific pin mapping is detailed in the RAK5010 schematic and RUI3 pin definition header files. I2C sensors are commonly used for tracking-related data like motion or temperature.
