STMicroelectronics X-NUCLEO-S2915A1 Expansion Board S2-LP Sub GHz Evaluation Kit for STM32 Nucleo 940 MHz

The STMicroelectronics X-NUCLEO-S2915A1 expansion board is based on the S2-LP radio and operates in the 915 MHz ISM frequency band. The expansion board is compatible with ST morpho and Arduino UNO R3 connectors. The X-NUCLEO-S2915A1 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.
