STMicroelectronics X-STM32MP-MSP01

Overview

X-STM32MP-MSP01 from STMicroelectronics is a multisensor evaluation board integrating motion (ISM330DHCX 6-axis IMU, IIS2DLPC industrial accelerometer), environmental (LPS22HH pressure sensor, STTS22H temperature sensor), ambient light (VD6283TX), and Time-of-Flight (VL53L5CX multizone ranging) sensors, plus a digital microphone (MP23DB02MM) and dynamic NFC/RFID tag (ST25DV64KC). It interfaces via 40-pin GPIO connector using I²C, SPI, and GPIO signals for STM32MP157F-DK2 and Raspberry Pi platforms.

For engineers reviewing the X-STM32MP-MSP01 datasheet, X-STM32MP-MSP01 pinout, X-STM32MP-MSP01 application, or X-STM32MP-MSP01 equivalent, this board supports rapid prototyping of sensor fusion, industrial condition monitoring, AR/VR spatial awareness, and smart wearable systems with OpenSTLinux software expansion (X-LINUX-MSP1).

Technical Context

The board implements parallel I²C buses for concurrent sensor access: ISM330DHCX, IIS2MDC, LPS22HH, STTS22H, VD6283TX, and VL53L5CX share I²C1 (SCL/SDA), while ST25DV64KC uses the same bus with configurable GPO signaling. Dedicated interrupt lines (INT_DRDY, INT1/INT2) enable low-latency event-driven sampling across all six sensors and microphone.

It provides dual-voltage domain support (1.8 V for MEMS sensors and ToF, 3.3 V for NFC and logic), level-shifted I/O via ST2378E1 translators, and flexible signal routing through DIL24 socket (SPI CS/CLK/MISO/MOSI, GPIOs) and flex connectors for adapter integration.

FAQ

Does X-STM32MP-MSP01 require external power or draw from the host board?

X-STM32MP-MSP01 is powered entirely from the host 5 V and 3.3 V rails via the 40-pin GPIO connector; no external power supply is needed. On-board LDK130M-R generates regulated 1.8 V for MEMS and ToF sensors, while 3.3 V powers NFC, EEPROM, and logic. Voltage domains are isolated and decoupled per ST reference design guidelines.

Which software framework is officially supported for sensor data acquisition?

ST provides the X-LINUX-MSP1 OpenSTLinux software expansion package, including kernel drivers (IIO subsystem), userspace HAL libraries, Python/C APIs, and prebuilt Yocto images with sensor fusion demos. It supports real-time streaming, calibration, and synchronized multi-sensor timestamping via STM32MP1 hardware timers.

Can the DIL24 socket be used for custom SPI peripherals beyond ST's reference adapters?

Yes - the DIL24 socket exposes SPI_CS, SPI_CLK, SPI_MISO, SPI_MOSI, and two GPIOs (FLEX_INT1/FLEX_INT2), enabling connection of third-party SPI sensors or actuators. Signal levels are 1.8 V tolerant, and routing follows ST's schematic-defined net names; no level translation is provided on those pins.

Is the VL53L5CX ToF sensor configured for single-zone or multizone operation out of the box?

The VL53L5CX is factory-configured and software-enabled for 8×8 multizone ranging (64 zones) with full API access via ST's X-CUBE-TOF1 middleware. Default firmware delivers calibrated distance, confidence, and ambient light rejection per zone, with runtime reconfiguration supported through I²C register writes.
