Description

The X-NUCLEO-BNRG2A1 expansion board provides Bluetooth low energy

connectivity for developer applications and can be plugged onto an STM32 Nucleo

development board (e.g., NUCLEO-L476RG with ultra-low power STM32

microcontroller) through its Arduino UNO R3 connectors.

The expansion board features the Bluetooth

v5.0 compliant and FCC certified

BlueNRG-M2SP application processor module based on the ST BlueNRG-2 System-

on-Chip. This SoC manages the complete Bluetooth low energy stack and protocols

on its Cortex-M0 core and programmable Flash, which can accommodate custom

applications developed using the SDK. The BlueNRG-M2SP module supports master

and slave modes, increased transfer rates with data length extension (DLE), and

AES-128 security encryption.

The X-NUCLEO-BNRG2A1 interfaces with the STM32 Nucleo microcontroller via SPI

connections and GPIO pins, some of which can be configured by the hardware.
