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.
Key Product on board
• BLUENRG-M2SP Bluetooth Low Energy, FCC and IC certified (FCC ID:
S9NBNRGM2SP, IC: B976C-BNRGM2SP), module based on Bluetooth® Low Energy
wireless network processor BlueNRG-2, BLE v5.0 compliant.
• BLUENRG-M2SP integrates a BALF-NRG-02D3 balun and a PCB antenna. It embeds
32 MHz crystal oscillator for the BlueNRG-2.
• M95640-RMC6TG 64-Kbit serial SPI bus EEPROM with high-speed clock interface
