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
