Product overview

Key Benefits

Easy to use

Module already certified, RF already fine-tuned, and product fully integrated in CubeMX. Plug in to enable ready-to-go wireless connectivity.

Ultra-low-power consumption

Low-power PA optimized for low-power radio performance and module leveraging the STM32WL5 SoC ultra-low-power architecture.

Long range radio performance

High-power LoRa radio and PA with long-range communication reduces gateway requirements and infrastructure costs.


The B-WL5M-SUBG1 STM32WL connectivity expansion board provides an affordable and flexible way for users to try out new concepts and build prototypes with the STM32WL series STM32WL5MOC microcontroller module.

The B-WL5M-SUBG1 product requires a separate probe for programming and debugging. The STLINK-V3SET debugger can be connected through a MIPI10/STDC14 cable.

The B-WL5M-SUBG1 STM32WL connectivity expansion board is provided with a USB Type-C® connector on an add-on STMod+ adapter board.

The B-WL5M-SUBG1 product is provided with the STM32WL comprehensive software HAL library and various packaged software examples available with the STM32CubeWL MCU Package.
