Waveshare BG95 EVB Development Board w/ BG95-M3 LTE Cat M1/NB2 & GNSS

The board is designed for QuecPython development, a Python 3 variant optimized for Quectel modules. You can program it using the provided QPYcom tool, Thonny IDE plugin, or VSCode plugin. It also supports standard AT commands over its serial interface for basic modem control. The ARM Cortex A7 processor runs the ThreadX real-time operating system, providing the underlying execution environment.

Insert a 1.8V nano-SIM card from a supported LTE-M/NB-IoT provider into the onboard slot. Power the board via the USB Type-C port. Using a serial terminal or QuecPython script, send AT commands to initialize the module (AT+CFUN=1), register on the network (AT+CREG?), and activate a PDP context for data. You can then use built-in protocol stacks like TCP or MQTT through the provided socket or MQTT client libraries in QuecPython.

Yes, the board features a 40-pin GPIO header that is electrically and physically compatible with most Raspberry Pi HATs. This allows you to directly connect sensors, displays, ADCs, and other peripherals designed for the Raspberry Pi ecosystem. Note that you will interface with these accessories through QuecPython GPIO libraries or direct register access, not Raspberry Pi OS.

The BG95-M3 module and board are designed for ultra-low power IoT applications. You can place the module into various PSM (Power Saving Mode) and eDRX (extended Discontinuous Reception) states using AT commands (e.g., AT+CPSMS, AT+CEDRXS). Typical average current can be reduced to microamps in deep sleep. For optimal battery life, design your application to transmit data in bursts and maximize time in low-power modes, using the GNSS only when needed.
