ST UM3039 User manual

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.

7Regulatory compliance information
Formal Notices Required by the U.S. Federal Communications Commission (FCC)
This kit is designed to allow:
(1) Product developers to evaluate electronic components, circuitry, or software associated with the kit to
determine whether to incorporate such items in a finished product and
(2) Software developers to write software applications for use with the end product.
This kit is not a finished product and when assembled may not be resold or otherwise marketed unless all
required FCC equipment authorizations are first obtained. Operation is subject to the condition that this product
not cause harmful interference to licensed radio stations and that this product accept harmful interference. Unless
the assembled kit is designed to operate under part 15, part 18 or part 95 of this chapter, the operator of the kit
must operate under the authority of an FCC license holder or must secure an experimental authorization under
part 5 of this chapter 3.1.2.
Formal Product Notice Required by Industry Canada
For evaluation purposes only. This kit generates, uses, and can radiate radio frequency energy and has not been
tested for compliance with the limits of computing devices pursuant to Industry Canada (IC) rules.
À des fins d'évaluation uniquement. Ce kit génère, utilise et peut émettre de l'énergie radiofréquence et n'a pas
été testé pour sa conformité aux limites des appareils informatiques conformément aux règles d'Industrie Canada
