STMicroelectronics Sub-1 GHz 868 MHz RF Expansion Board Based on S2-LP Radio for STM32 Nucleo X-NUCLEO-S2868A1 Wireless

The X-NUCLEO-S2868A1 expansion board is based on the S2-LP radio and operates in the 868 MHz ISM frequency band. The expansion board is compatible with ST morpho and Arduino UNO R3 connectors. The X-NUCLEO-S2868A1 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.
