Bluetooth Low Energy expansion board
Hardware Overview
X-NUCLEO-BNRG2A1 Hardware Description
• The X-NUCLEO-BNRG2A1 is a Bluetooth Low Energy (BLE) evaluation and
development board system, designed around ST’s BLUENRG-M2SP Bluetooth
Low Energy module based on BlueNRG-2.
• The BlueNRG-2 processor hosted in the BLUENRG-M2SP module communicates
with the STM32 microcontroller, hosted on the Nucleo development board,
through an SPI link available on the Arduino UNO R3 connector.
