STMicroelectronics STEVAL-MKI161V1

Overview

STEVAL-MKI161V1 from STMicroelectronics is an adapter evaluation board designed to interface the LSM6DS0 3-axis accelerometer and 3-axis gyroscope MEMS inertial sensor to a standard DIL24 socket. It provides full pinout access, integrated VDD decoupling capacitors, and mechanical compatibility with STEVAL-MKI109V2/V3 motherboards for rapid prototyping in motion-sensing applications such as wearable activity trackers and industrial vibration monitors.

For engineers reviewing the STEVAL-MKI161V1 datasheet, STEVAL-MKI161V1 pinout, STEVAL-MKI161V1 application, or STEVAL-MKI161V1 equivalent, this adapter enables direct LSM6DS0 evaluation without custom PCB design-supporting SPI/I²C communication, real-time sensor data streaming via Unico GUI, and integration into existing DIL24-based development platforms.

Technical Context

The STEVAL-MKI161V1 implements a passive breakout architecture: it maps all 24 pins of the LSM6DS0's LGA-24 package to a standard 0.6-inch DIL24 footprint, preserving signal integrity for both digital interfaces (SPI and I²C) and analog supply/ground paths. No active components or level-shifting circuitry are included-only decoupling capacitors on VDD.

It functions exclusively as a mechanical and electrical translation layer between the surface-mount LSM6DS0 and through-hole DIL24 sockets used on ST's STEVAL-MKI109V2 and STEVAL-MKI109V3 motherboard platforms. The board lacks onboard microcontroller, voltage regulation, or USB interface-relying entirely on the host motherboard for power, clock, and host communication.

FAQ

Does the STEVAL-MKI161V1 include a microcontroller or USB interface?

No. The STEVAL-MKI161V1 is a passive adapter board with no active components. It relies entirely on a compatible motherboard (e.g., STEVAL-MKI109V2/V3) for microcontroller processing, USB-to-serial bridging, and power delivery. Its sole function is mechanical and electrical pin mapping from LSM6DS0's LGA-24 to DIL24.

Can the STEVAL-MKI161V1 be used independently without a motherboard?

No. It lacks power regulation, clock generation, and host interface circuitry. Operation requires insertion into a supported motherboard that supplies regulated VDD, provides SPI/I²C host control, and connects to a PC via USB. Standalone use is not supported.

What software tools support the STEVAL-MKI161V1?

The board is fully supported by ST's Unico GUI, a free Windows application enabling real-time visualization, configuration, and data logging of LSM6DS0 registers over SPI or I²C. It also works with ST's X-CUBE-MEMS1 firmware library for custom embedded implementations on STM32 hosts.

Is the STEVAL-MKI161V1 pinout identical to the LSM6DS0 LGA-24 package?

Yes. All 24 terminals-including VDD, GND, SDA, SCL, CS, SDO, INT1, INT2, and NC pins-are mapped one-to-one to the DIL24 socket footprint. Pin numbering follows the standard DIL24 convention, matching the physical layout shown in Figure 1 of DocID027551 Rev 2.
