STMicroelectronics B-WBA5M-WPAN STM32WBA Connectivity Expansion Board

STMicroelectronics B-WBA5M-WPAN STM32WBA Connectivity Expansion Board provides an affordable and flexible way for users to try out new concepts and build prototypes with the STM32WBA series STM32WBA5MMGH6 module. The B-WBA5M-WPAN product requires a separate probe for programming and debugging. The STLINK-V3SET debugger can be connected through an STDC14 cable.

The B-WBA5M-WPAN STM32WBA connectivity expansion board integrates a USB Type-C® connector for power only. It also incorporates an M.2 E-Key connector into an M.2 E-Key daughterboard. This daughterboard provides a BLUETOOTH® interface to a host board including an M.2 E-Key host connector.

The M.2 E-Key connector follows the PCI-SIG standard and provides UART, SPI, I2C, and SAI interfaces for communication with the host. The STMicroelectronics B-WBA5M-WPAN includes the comprehensive STM32WBA software HAL library and various packaged software examples with the STM32CubeWBA MCU package.
