Sales Briefcase
  • 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.

    Key Features

    • Based on the BlueNRG-M2SP module FCC certified module (FCC ID: S9NBNRGM2SP and IC: B976C-BNRGM2SP)
    • Compatible with STM32 Nucleo boards
    • Equipped with Arduino UNO R3 connector
    • Scalable solution, capable of cascading multiple boards for larger systems
    • Free comprehensive development firmware library and examples for BlueNRG-2 compatible with STM32Cube
    • BlueNRG-M2SP:
      • Bluetooth v5.0 compliant
      • Supports master and slave modes
      • BLE data packet length extension
      • Embedded BALF-NRG-02D3 integrated matched balun with harmonic filter
    • Interfaces:
      • 1 UART, 1 I²C, 1 SPI, 14 GPIOs, 2 multifunction timers, 10-bit ADC, Watchdog & RTC, DMA controller, PDM stream processor, SWD debug interface
    • Small form factor: 11.5mmx13.5mm
    • Complemented with Bluetooth low energy protocol stack library (GAP, GATT, SM, L2CAP, LL)
    • AES security co-processor
    • Bluetooth low energy SDK with a wide range of profiles
    • Embedded BlueNRG-2 BLE SoC:
      • High performance, ultra-low power Cortex-M0 32-bit based core
      • Programmable embedded 256 KB Flash
      • 24 KB embedded RAM with data retention
      • Up to +8 dBm available output power
      • Down to -88 dBm Rx sensitivity
      • Up to 96 dB link budget with excellent link reliability
