Description

The 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.
