STMicroelectronics STEVAL-MKI076V1

Overview

STEVAL-MKI076V1 from STMicroelectronics is an adapter board for LY3200ALH MEMS sensors, enabling plug-in evaluation via standard DIL-24 socket. It provides full LY3200ALH pinout, on-board VDD decoupling capacitors, and direct compatibility with STEVAL-MKI109V2 motherboard for PC-based sensor characterization using Unico GUI.

For engineers reviewing the STEVAL-MKI076V1 datasheet, STEVAL-MKI076V1 pinout, STEVAL-MKI076V1 application, or STEVAL-MKI076V1 equivalent, this board serves as a rapid prototyping interface between LY3200ALH devices and host microcontroller systems-particularly where MEMS signal integrity, power rail stability, and socket-based test flexibility are critical.

Technical Context

The board implements a passive, zero-logic adapter: no active components, no firmware, and no voltage translation. All LY3200ALH signals-including VDD, GND, SCL, SDA, INT1, INT2, and analog outputs-are routed 1:1 to DIL-24 footprint pins with dedicated 100 nF ceramic decoupling on VDD.

Designed exclusively for use with STEVAL-MKI109V2, it relies on that motherboard's STM32F303VC MCU to handle I²C communication, interrupt handling, and USB-to-PC data streaming-making the adapter functionally transparent in the sensor evaluation chain.

FAQ

Does STEVAL-MKI076V1 include a microcontroller or firmware?

No. It is a passive adapter board with no active components, no embedded processor, and no firmware. All control, communication, and data processing must be handled externally-specifically by the STEVAL-MKI109V2 motherboard's STM32F303VC MCU and associated Unico GUI software stack.

Can STEVAL-MKI076V1 be used without STEVAL-MKI109V2?

No. The board lacks power regulation, USB interface, I²C master logic, or any means to communicate with a PC. Its sole functional purpose is to electrically and mechanically bridge LY3200ALH sensors to STEVAL-MKI109V2-no alternative host interface is supported or documented.

What is the role of the 100 nF capacitor on VDD?

It provides local high-frequency decoupling for the LY3200ALH sensor's power supply, minimizing noise coupling from the host motherboard's power distribution network. This capacitor is placed directly at the DIL-24 socket's VDD pin per ST's LY3200ALH layout recommendations and is required for stable sensor operation during evaluation.

Is STEVAL-MKI076V1 still in active production?

No. As confirmed in DocID17680 Rev 2 (July 2013), STMicroelectronics has marked STEVAL-MKI076V1 as Obsolete. Aetrix Electronics maintains limited legacy stock for design continuity and replacement needs but does not offer new production builds or long-term supply guarantees.
