Product details

Overview

STEVAL-MKI032V1 from STMicroelectronics is an interconnection board designed to bridge STM32xxx evaluation boards and STEVAL-MKI0xxVx MEMS accelerometer demonstration boards via a DIL24 socket. It supports both analog (LIS344ALH, LIS244AL, LIS302SG) and digital (LIS302DL, LIS3LV02DL) MEMS sensors, provides full SPI/I²C and interrupt signal routing, and enables real-time sensor data acquisition and LCD/USB-based visualization using included STM32-MEMS firmware.

For engineers reviewing the STEVAL-MKI032V1 datasheet, STEVAL-MKI032V1 pinout, STEVAL-MKI032V1 application, or STEVAL-MKI032V1 equivalent, this board serves as a validated hardware interface for rapid prototyping of motion-sensing systems with STM32 microcontrollers, supporting inclination measurement, interrupt-driven sensing, and dual-interface sensor evaluation without custom PCB design.

Technical Context

The board implements passive signal routing-no active logic or level-shifting-between STM32 GPIOs and MEMS sensor terminals. All axes (X/Y/Z), power-down (PD), full-scale (FS), clock (SCL/CLK), data (SDA/SDO), chip select (CS), and two interrupt lines (INT1/INT2) are directly mapped between the DIL24 socket and the 20-pin header connecting to STM32 evaluation boards.

It supports both analog output accelerometers (requiring ADC input on STM32) and digital accelerometers (using native SPI or I²C peripherals), with dedicated traces preserving signal integrity for timing-critical interfaces like SPI clock and interrupt edges.

Key Specifications

Parameter	Value and Actual Design Meaning
Form Factor	Interconnection board - no MCU or sensor onboard; functions solely as signal-mapping interface
MEMS Interface Socket	DIL24 socket - mechanically and electrically compatible with all STEVAL-MKI0xxVx boards
STM32 Interface	20-pin male header - maps to standard STM3210B-EVAL/STM3210E-EVAL expansion connectors
Digital Sensor Support	SPI and I²C - separate routed traces for SDO/SDA, SCL/CLK, CS, and dual INT lines
Analog Sensor Support	Three independent analog outputs (X/Y/Z), plus PD and FS control signals routed to STM32 GPIO/ADC pins
Firmware Included	STM32-MEMS library + demo apps - enables USB data streaming, LCD display, and interrupt handling out-of-box

FAQ

Does STEVAL-MKI032V1 include a microcontroller or MEMS sensor?

No. The board contains neither an MCU nor a sensor. It is a passive interconnection platform: one side accepts a STEVAL-MKI0xxVx MEMS demo board (e.g., STEVAL-MKI013V1 with LIS302DL), and the other connects to an STM32 evaluation board (e.g., STM3210B-EVAL) via its 20-pin expansion header. All processing and sensing occur on the attached boards.

Which STM32 evaluation boards are natively supported?

STEVAL-MKI032V1 is explicitly validated with STM3210B-EVAL (for STM32F103xB), STM3210E-EVAL (for STM32F103xE), and the IAR KickStart Kit™ for STM32 (STM3210B-SK/IAR). Compatibility relies on matching pinout and signal assignment of the 20-pin expansion interface defined in ST's evaluation board schematics.

Can it interface with non-ST MEMS sensors?

No. The DIL24 socket and signal routing are designed exclusively for ST's STEVAL-MKI0xxVx series boards (e.g., MKI013V1, MKI015V1). Pin assignments, voltage levels, and interface protocols (e.g., LIS302DL's SPI timing) are optimized for ST's MEMS devices and not guaranteed for third-party DIL24 sensors.

Is USB connectivity built into STEVAL-MKI032V1?

No. USB functionality is provided by the connected STM32 evaluation board (e.g., STM3210E-EVAL includes a USB connector and firmware stack). STEVAL-MKI032V1 routes only sensor signals (analog outputs, SPI/I²C, interrupts) to the STM32's GPIO, ADC, and peripheral pins-USB data transfer is handled entirely by the host MCU's firmware and hardware.
