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.
