STMicroelectronics Evaluation Board SPSGRF-868 RF Transceiver Evaluation Board for SPSGRF-868 868 MHz X-NUCLEO-IDS01A4

RF Expansion Boards based on SPSGRF-915 and SPSGRF-868 Modules for STM32 Nucleo, STMicroelectronics

The evaluation boards are based on the SPIRIT1 RF module SPSGRF-xxx, a Low data rate, low power Sub 1GHz transceiver. The SPSGRF-915 module operates in the 915MHz and the SPSGRF-868 module operates in the 868MHz ISM band. They are FCC certified and IC certified. It is compatible with the ST Morpho and Arduino UNO R3 connector layout. The board interfaces with the STM32 microcontroller via SPI connections and GPIO pins. The user can change some of the GPIOs by mounting or removing the resistors.
