X-NUCLEO-BNRG2A1 Hardware Description

Hardware Overview

� 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.

Setup & Application Examples
HW limitation
� Warning Even if not strictly required for the correct working of the BlueNRG-2 module, to correctly set the BlueNRG-2 RESET pin on pin D7 of the Arduino connector a 0 Ohm resistor must be soldiered on R117. Alternatively, the D7 pin and the pin #5 of the J12 on the X-NUCLEOBNRG2A1 expansion board must be bridged (as shown in the picture).

Setup & Application Examples
