Introduction
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.
