Hardware description

This section describes the X-NUCLEO-IDB05A1 features and provides information which
could be useful to understand the board schematic diagrams.
2.1

X-NUCLEO-IDB05A1 board

The board allows the user to test the functionality of the SPBTLE-RF module. The
SPBTLE-RF hosts the BlueNRG-MS, a very low power Bluetooth Low Energy (BLE) single-
mode network processor, compliant with Bluetooth specification v4.1. The module also
embeds the innovative BALF-NRG-01D3 (balun with integrated harmonic filter) and a chip
antenna.
Its functionality can be exploited using the firmware package contained in the X-CUBE-
BLE1. It is fundamental to program the microcontroller on the STM32 Nucleo board. Please
refer to user manuals UM1724 and UM1725, available on www.st.com.
The SPBTLE-RF module and the STM32 Nucleo board are connected through connectors
CN5, CN6, CN8 and CN9 (see
and X-NUCLEO-IDB05A1 left-side connectors"
asterisk (*) allow an alternative pin for that specific function, i.e. SPI_IRQ could be moved
from CN8.1 to CN5.2.
