Sub-1 GHz 868 MHz RF expansion board based on S2-LP radio for STM32 Nucleo

X-NUCLEUS-S2868A2

Overview

The X-NUCLEO-S2868A2 expansion board is based on the S2-LP ultra-low power RF transceiver and operates in the 868 MHz ISM frequency band.

The X-NUCLEO-S2868A2 interfaces with the STM32 Nucleo microcontroller via SPI connections and GPIO pins. You can change some of the GPIOs by mounting or removing the resistors.
The expansion board is compatible with ST morpho and Arduino UNO R3 connectors.
