Description
The X-NUCLEO-IDB05A2 Bluetooth low energy expansion board is based on the
BlueNRG-M0 BLE network processor module.
The BlueNRG-M0 is Bluetooth v4.2 compliant, FCC and IC certified (FCC ID:
S9NBNRGM0AL; IC: 8976C-BNRGM0AL). It supports simultaneous master/slave
roles and can behave as a Bluetooth low energy sensor and hub device at the same
time.
The BlueNRG-M0 provides a complete RF platform in a tiny form factor, with
integrated radio, antenna, high frequency and LPO oscillators.
The X-NUCLEO-IDB05A2 is compatible with the ST morpho (not mounted) and
Arduino UNO R3 connector layout.
The X-NUCLEO-IDB05A2 interfaces with the STM32 microcontroller via the SPI pin
and allows changing the default SPI clock, SPI chip select and SPI IRQ by replacing
a resistor on the expansion board.
