Getting started with the Sub-1 GHz expansion board based on

SPSGRF-868 and SPSGRF-915 modules for STM32 Nucleo

Introduction

The X-NUCLEO-IDS01A4 and X-NUCLEO-IDS01A5 are evaluation boards intended to

provide a platform for testing the features and capabilities of the SPSGRF modules, based

on the SPIRIT1 low data rate, low power sub-1 GHz transceiver device.

These expansion boards can be plugged into the Arduino UNO R3 connectors of any

STM32 Nucleo board. The user can mount ST Morpho connectors if required. Other

expansion boards can easily be stacked to allow evaluation of different devices using sub-1

GHz communication.

The boards are equipped with the following features:

• On-board SPSGRF module based on the SPIRIT1 sub-1 GHz transceiver device

• SPI EEPROM for saving parameters

• LED for user interface

• Jumper at 3V3 for checking the current consumption of the expansion board
