The X-STM32MP-IOT01E is an STM32 MPU expansion board that hosts the SPSGRF-868 SPIRIT1 RF module for Sub-1 GHz RF communication with sensor for IoT applications. The X-STM32MP-IOT01E interfaces with the STM32MP microcontroller via GPIO connector pins, using SPI, I²C, and GPIO connections for the SPSGRF-868, the LSM6DSOX iNEMO inertial module, keys, and LEDs. It is compatible with the STM32MP157F-DK2 and Raspberry Pi GPIO connector layout. The SPSGRF-868 CE certified module operates in the 868 MHz ISM band. It is based on the SPIRIT1 Sub-1GHz transceiver and the integrated balun (BALF-SPI-01D3). The LSM6DSOX iNEMO inertial module is a 3-axis digital accelerometer and a 3-axis digital gyroscope with a full-scale acceleration range of ±2/±4/±8/±16 g and an angular rate range of ±125/±250/±500/±1000/±2000 dps.
