Product details
Overview
STEVAL-MKI218V1 from STMicroelectronics is an adapter evaluation board for the AIS2IH 3-axis digital accelerometer, designed specifically for automotive-grade motion sensing applications. It provides full DIL24 socket compatibility, complete AIS2IH pinout access, integrated decoupling (10 µF + dual 100 nF), and seamless interoperability with the STEVAL-MKI109D host platform.
For engineers reviewing the STEVAL-MKI218V1 datasheet, STEVAL-MKI218V1 pinout, STEVAL-MKI218V1 application, or STEVAL-MKI218V1 equivalent, this board enables rapid prototyping of automotive crash detection, rollover sensing, and eCall system integration using ST's high-performance MEMS sensor interface.
Technical Context
The board implements a passive, unpowered signal-translation interface between the AIS2IH (LGA-12, 2×2 mm) and a standard 24-pin DIL socket, preserving all functional pins including dual interrupt outputs (INT1/INT2), I²C (SCL/SDA), SPI (CS/SCL/SDA/SA0), and dual power domains (VDD, VDDIO). No level-shifting or active logic is used.
It is engineered exclusively as a mechanical and electrical breakout-no onboard microcontroller, voltage regulation, or firmware. Its design intent is to provide direct, low-noise, layout-optimized access to AIS2IH signals for validation on third-party test systems or the STEVAL-MKI109D bridge platform.

FAQ
Does STEVAL-MKI218V1 include an onboard microcontroller or firmware?
No. The board contains only passive components and routing traces. It has no MCU, flash memory, or embedded code. It functions solely as a pinout adapter to connect the AIS2IH sensor to external hosts like the STEVAL-MKI109D or custom test systems via DIL24 socket.
Can STEVAL-MKI218V1 be used without the STEVAL-MKI109D platform?
Yes. While optimized for use with STEVAL-MKI109D, it can interface directly with any DIL24-compatible test fixture or custom carrier board supporting AIS2IH's I²C/SPI protocols, dual interrupts, and dual-supply (VDD/VDDIO) requirements.
What is the purpose of the dual 100 nF capacitors on the VDD line?
These capacitors provide high-frequency noise suppression for the AIS2IH's analog MEMS core and digital interface circuitry, ensuring stable operation during transient acceleration events and minimizing measurement jitter in automotive environments.
Is STEVAL-MKI218V1 qualified for automotive production use?
No. It is an evaluation adapter board-not a production-grade module. It lacks AEC-Q200 qualification, conformal coating, or extended temperature range validation. It supports development and lab validation only, not end-equipment deployment.
