STMicroelectronics STEVAL-MKI050V1

Overview

STEVAL-MKI050V1 from STMicroelectronics is an adapter board for the LPY550ALH single-axis analog gyroscope, enabling plug-in evaluation via standard DIL-24 socket. It provides full pinout access, on-board VDD decoupling capacitors, RoHS compliance, and mechanical compatibility with ST's family of MEMS sensor adapter boards.

For engineers reviewing the STEVAL-MKI050V1 datasheet, STEVAL-MKI050V1 pinout, STEVAL-MKI050V1 application, or STEVAL-MKI050V1 equivalent, this board supports rapid prototyping of angular rate sensing in industrial motion control, robotics stabilization, and handheld device orientation systems without PCB redesign.

Technical Context

The board implements a passive breakout interface between the LPY550ALH MEMS gyroscope (in 24-pin LGA package) and a standard DIL-24 socket footprint. It routes all 24 signals-including VDD, GND, OUT, REF, FILT_IN, FILT_OUT, and test points-with no active circuitry or signal conditioning.

Designed exclusively for evaluation, it includes only ceramic decoupling capacitors on the VDD line and maintains identical pin mapping across ST's MKI-series adapter boards, allowing direct substitution among LY550ALH, LY550AH, and similar sensors during comparative testing.

FAQ

Does STEVAL-MKI050V1 include the LPY550ALH sensor?

Yes - the board ships with the LPY550ALH gyroscope pre-mounted and soldered. It is not a bare adapter; the sensor is factory-installed and tested, making it immediately usable for analog output evaluation without additional component sourcing or assembly.

Can STEVAL-MKI050V1 be used with other ST gyroscope adapters?

Yes - its pinout and mechanical layout are fully compatible with other STEVAL MKI-series adapter boards (e.g., STEVAL-MKI051V1 for LY550AH), enabling seamless sensor swapping in the same DIL-24 socket without hardware modification or rework.

What is the function of the FILT_IN and FILT_OUT pins on this board?

These pins provide external access to the LPY550ALH's internal low-pass filter network. FILT_IN connects to the filter input node, and FILT_OUT to the filtered output - allowing users to modify cutoff frequency or add external filtering stages for custom bandwidth control.

Is STEVAL-MKI050V1 still in active production?

No - STMicroelectronics has marked STEVAL-MKI050V1 as obsolete (per Doc ID 17000 Rev 1). However, Aetrix Electronics maintains legacy inventory and offers technical support, traceable sourcing, and lifecycle coordination for ongoing design-in and maintenance use cases.
