Product details
Overview
STEVAL-MKI229A from STMicroelectronics is a DIL24 socket-compatible adapter board for the LSM6DSO16IS 6-axis IMU with integrated ISPU, providing full pin access, on-board decoupling (100 nF on VDD), and direct plug-in capability for rapid prototyping of motion-sensing applications in IoT edge nodes.
For engineers reviewing the STEVAL-MKI229A datasheet, STEVAL-MKI229A pinout, STEVAL-MKI229A application, or STEVAL-MKI229A equivalent, this board enables immediate sensor evaluation via the STEVAL-MKI109D host platform and MEMS Studio GUI-no custom PCB design or soldering required.
Technical Context
The STEVAL-MKI229A implements a passive breakout interface between the LSM6DSO16IS QFN-24 package and a standard 24-pin dual-in-line socket, preserving all signal integrity paths including dedicated VDD/VDDIO power domains, two interrupt outputs (INT1/INT2), I²C (SCL/SDA), SPI (CS/SCL/SDA/SDO), and ISPU configuration pins (MSCL/MSDA/SDO/SA0).
It integrates two 100 nF ceramic decoupling capacitors on the VDD rail and uses zero-ohm resistors (RES10/RES11) to configure SDO/SA0 and interrupt routing, supporting both I²C and SPI communication modes without hardware modification.

FAQ
Does STEVAL-MKI229A require external power or firmware to operate?
No. The board draws regulated 1.8 V or 3.3 V power from the host platform (e.g., STEVAL-MKI109D) and contains no active circuitry or firmware. It functions solely as a passive pin-mapped adapter with decoupling capacitors and configurable jumpers.
Can STEVAL-MKI229A be used without the STEVAL-MKI109D platform?
Yes - it can interface directly with any host system providing compatible voltage levels (VDD: 1.71–3.6 V; VDDIO: 1.08–3.6 V), I²C/SPI signals, and interrupt handling. However, MEMS Studio GUI support and out-of-box functionality require the STEVAL-MKI109D bridge MCU.
What is the purpose of RES10 and RES11 on the board?
RES10 and RES11 are zero-ohm resistors that configure the SDO/SA0 pin function and interrupt routing options. RES10 selects SDO (SPI MISO) or SA0 (I²C address LSB); RES11 determines whether INT1 is routed to JP1 pin 3 or JP2 pin 4, enabling flexible host connection mapping.
Is the STEVAL-MKI229A compatible with other LSM6DSO-series sensors?
No - it is mechanically and electrically optimized exclusively for the LSM6DSO16IS in its QFN-24 package. Pin pitch, pad layout, and ISPU-specific signal assignments (e.g., MSCL/MSDA) differ from other variants like LSM6DSOX or LSM6DSR, making cross-sensor use unsupported.
