Introduction
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 for power only 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.
