Product overview

Key Benefits

All-in-one hardware

Design and test with rich functionalities: MEMS sensors, LEDs, flexible power supply, and optional SMA connector.

Effortless BLE adoption

Integrate BLE connectivity to applications by using the STM32WB1MMC module, already certified and within the 10 years longevity program.

Open-source success

B-WB1M-WPAN1 supports IDEs like IAR Embedded Workbench®, MDK-ARM, STM32CubeIDE and online resources like ST Wiki and STM32CubeWB.


The B-WB1M-WPAN1 STM32WB connectivity expansion board provides an affordable and flexible way for users to try out new concepts and build prototypes with the STM32WB series STM32WB1MMC microcontroller module.

The B-WB1M-WPAN1 product requires a separate probe for programming and debugging. The STLINK-V3SET debugger can be connected through a MIPI10/STDC14 cable.

The B-WB1M-WPAN1 STM32WB connectivity expansion board is provided with a USB Type-C® connector (for power only) on an add-on STMod+ adapter board.

The B-WB1M-WPAN1 product is provided with the STM32WB comprehensive software HAL library and various packaged software examples available with the STM32CubeWB MCU Package.
