Introduction
The X-STM32MP-IOT01A is a 40-pin connector expansion board for the STM32MP157F-DK2 discovery kit. The board features
the SPIRIT1 SPSGRF-915 RF module for Sub-1 GHz RF communication and the LSM6DSOX iNEMO inertial module for IoT
applications.
The X-STM32MP-IOT01A interfaces with the STM32MP157F-DK2 microprocessor via GPIO connector pins. It uses SPI, I²C,
GPIO connections for SPSGRF-915, iNEMO inertial module, switches, and LED.
The expansion board is compatible with both the STM32MP157F-DK2 and Raspberry Pi GPIO connector layout.

2Overview
The X-STM32MP-IOT01A operates in the 915 MHz ISM band.
The LSM6DSOX iNEMO inertial module is used for the motion detection.
The X-STM32MP-IOT01A interfaces with the STM32MP157F-DK2 via the 40-pin GPIO connector pins. It uses
SPI, I²C, and GPIO connections for the SPSGRF-915,LSM6DSOX, keys, and LED.
Figure 2. System block diagram
The X-STM32MP-IOT01A on-board devices are controlled through the STM32MP157F-DK2 using various
peripheral pins available on the GPIO connector.
The SPSGRF-915 interfaces with the STM32MP157F-DK2 using the SPI.
The I²C interface is used to interact with the LSM6DSOX.
The RGB LED and switches control through GPIOs is used for the user interface. Table 6 shows the configuration
of the GPIO connector pins to connect the various devices.
The X-STM32MP-IOT01A embeds the following key devices:
•SPSGRF-915: based on the SPIRIT1 device, which is a low data rate, low-power sub-GHz transceiver.
The SPIRIT1 operates both in the license-free ISM and SRD frequency bands at 169, 433,868 MHz, and
915 MHz. The SPSGRF-915 module is an FCC and IC certified module (FCC ID: S9NSPSGRF and IC:
8976C-SPSGRF). It interfaces with the STM32 Nucleo development boards through an SPI interface and
some GPIOs. The SPSGRF-915 module also integrates the BALF-SPI-01D3 balun and a chip antenna.

performance in high-performance mode. It enables always-on low-power features for an optimal motion
experience for the consumer. The LSM6DSOX has a full-scale acceleration range of ±2/±4/±8/±16 g and an
angular rate range of ±125/±250/±500/±1000/±2000 dps. It fully supports EIS and OIS applications as the
module includes a dedicated configurable signal processing path for OIS and the auxiliary SPI, configurable
for both the gyroscope and accelerometer.
