Product details

Overview

STEVAL-MKI108V2 from STMicroelectronics is an evaluation adapter board for the L3GD20 3-axis gyroscope and LSM303DLHC 9-axis (3-axis accelerometer + 3-axis magnetometer + 3-axis gyroscope) MEMS sensor module, designed to plug directly into a standard DIL-24 socket with full pin access, decoupling capacitors pre-mounted, and compatibility with STEVAL-MKI109V2/V3 motherboards.

For engineers reviewing the STEVAL-MKI108V2 datasheet, STEVAL-MKI108V2 pinout, STEVAL-MKI108V2 application, or STEVAL-MKI108V2 equivalent, this adapter enables rapid prototyping of motion-sensing systems using ST's 9-axis sensor fusion architecture with PC-based GUI (Unico) or custom firmware via USB-to-bridge MCU interface.

Technical Context

The board implements passive signal routing between the L3GD20 (SPI/I²C gyro) and LSM303DLHC (I²C accel/mag) and a DIL-24 footprint, preserving all critical sensor signals including SDA, SCL, INT1/INT2, DRDY, VDD, Vdd_IO, and PLLFILT. No level-shifting or active logic is integrated - it is a direct pin-mapped mechanical and electrical interface.

It relies entirely on external host control: the STEVAL-MKI109V2/V3 motherboards provide the STM32-based bridge MCU, USB interface, and firmware stack; this board contributes no processing, memory, or power regulation beyond basic decoupling (10 µF, 4.7 µF, 100 nF, 470 nF, 10 nF, 0.22 µF ceramics).

Key Specifications

Parameter	Value and Actual Design Meaning
Form Factor	DIL-24 socket-mount adapter board - enables direct insertion into standard 24-pin dual-in-line test sockets for breadboard-free sensor evaluation.
Sensor Support	L3GD20 (±250/±500/±2000 dps gyro) and LSM303DLHC (±2/±4/±8 g accel, ±1.3/±1.9 gauss mag) - full pinout exposed for simultaneous I²C/SPI access.
Power Decoupling	Integrated 10 µF (Vdd_IO), 4.7 µF (VDD), 100 nF, 470 nF, 10 nF, and 0.22 µF ceramic capacitors - ensures stable supply filtering per MEMS device requirements.
Interface Compatibility	Fully compatible with STEVAL-MKI109V2 and STEVAL-MKI109V3 motherboards - uses same pin mapping and signal naming for seamless stacking and firmware reuse.
Compliance	RoHS-compliant PCB assembly - meets EU Directive 2011/65/EU for hazardous substances in electronics.

FAQ

Does STEVAL-MKI108V2 include an onboard microcontroller or USB interface?

No. The board contains only passive components and routing traces. It requires connection to a STEVAL-MKI109V2 or STEVAL-MKI109V3 motherboard (which hosts an STM32 MCU and USB interface) to enable communication with a PC or host system.

Can STEVAL-MKI108V2 be used independently without a motherboard?

No. It lacks power regulation, clock generation, and digital interface circuitry. All sensor communication must be driven externally - the board serves solely as a breakout and socket interface for the L3GD20 and LSM303DLHC dies.

What software tools support STEVAL-MKI108V2?

ST's Unico GUI (Windows-based) and STSW-MKI109 software package provide real-time sensor data visualization, register configuration, and firmware upload capability - both require use with STEVAL-MKI109V2/V3 motherboards.

Is STEVAL-MKI108V2 pin-compatible with other ST evaluation adapters like STEVAL-MKI108V1?

No. STEVAL-MKI108V2 is specifically designed for L3GD20 + LSM303DLHC and uses a unique DIL-24 pin mapping. Earlier versions (e.g., MKI108V1) target different sensor combinations and are not mechanically or electrically interchangeable.
