STMicroelectronics STEVAL-MKI110V1

Overview

STEVAL-MKI110V1 from STMicroelectronics is an adapter board for the AIS328DQ 3-axis analog-output MEMS accelerometer, providing full pin access via a standard DIL-24 socket. It includes on-board decoupling (10 µF + 100 nF) on VDD, supports I²C/SPI interface modes via SPC/SCL, SDI/SDO/SDA and CS pins, and is designed for direct integration with the STEVAL-MKI109V2 motherboard for PC-based sensor evaluation.

For engineers reviewing the STEVAL-MKI110V1 datasheet, STEVAL-MKI110V1 pinout, STEVAL-MKI110V1 application, or STEVAL-MKI110V1 equivalent, this board enables rapid prototyping of motion-sensing systems using the AIS328DQ in industrial condition monitoring, wearable gesture interfaces, and vibration analysis test setups.

Technical Context

The STEVAL-MKI110V1 implements a passive breakout interface between the AIS328DQ LGA-24 package and a DIL-24 socket, preserving all signal, power, and interrupt terminals-including dual interrupt outputs (INT_1, INT_2), configurable I/O supply (VDD_IO), and mode-selectable serial interface (SPI/I²C via SDO/SA0). No active logic or level-shifting circuitry is integrated.

It is mechanically and electrically optimized for use with the STEVAL-MKI109V2 motherboard, where the onboard STM32F103 microcontroller handles USB-to-sensor communication and hosts the Unico GUI firmware stack-enabling real-time analog output streaming and register configuration without custom host software development.

FAQ

Does STEVAL-MKI110V1 include the AIS328DQ sensor IC?

No. The STEVAL-MKI110V1 is a bare adapter board only. It does not include the AIS328DQ IC - users must source and mount the AIS328DQ separately into the DIL-24 socket. The board provides correct footprint, routing, and decoupling but no pre-mounted sensor.

Can STEVAL-MKI110V1 operate standalone without STEVAL-MKI109V2?

No. The board lacks power regulation, USB interface, or microcontroller. It requires connection to the STEVAL-MKI109V2 motherboard (or equivalent host with compatible DIL-24 socket and signal routing) to provide power, communication, and firmware control for the AIS328DQ.

What is the purpose of JP1 and JP2 headers on STEVAL-MKI110V1?

JP1 and JP2 are 12-pin male headers that expose all AIS328DQ signals (power, analog outputs, interrupts, serial interface) for probing, oscilloscope measurement, or custom interconnection. They replicate the DIL-24 pinout in dual-row 0.1" spacing for breadboard or test fixture use.

Is STEVAL-MKI110V1 RoHS compliant?

Yes. As stated in the official ST data brief (DocID18707 Rev 2), the STEVAL-MKI110V1 is RoHS compliant, meeting EU Directive 2011/65/EU requirements for restriction of hazardous substances in electrical and electronic equipment.
