STMicroelectronics STEVAL-MKI215V1

Overview

STEVAL-MKI215V1 from STMicroelectronics is an adapter board for the LSM6DSO32 6-axis IMU, providing full DIL24 socket compatibility, complete pin access (including INT1/INT2, CS, SCL/SDA, SDO, OCS, VDD/VDDIO), and pre-mounted decoupling capacitors for immediate evaluation. It enables rapid prototyping of motion-sensing applications in wearables and compact embedded systems.

For engineers reviewing the STEVAL-MKI215V1 datasheet, STEVAL-MKI215V1 pinout, STEVAL-MKI215V1 application, or STEVAL-MKI215V1 equivalent, this adapter supports direct integration with STEVAL-MKI109V3/STEVAL-MKI109D motherboards and X-NUCLEO-IKS4A1, and is optimized for MEMS Studio GUI-based sensor characterization and firmware development.

Technical Context

The STEVAL-MKI215V1 implements a passive breakout interface between the LSM6DSO32 QFN-24 package and a standard 24-pin dual-in-line socket, preserving all signal integrity paths including dedicated VDD and VDDIO power rails, independent ground planes, and configurable interrupt outputs (INT1/INT2). It routes all 14 functional pins of the LSM6DSO32 without level-shifting or signal conditioning.

Designed as a mechanical and electrical bridge, it maintains native I²C/SPI communication capability, supports OCS (output clock selection) and SDO (serial data output) configuration, and provides solder jumpers (R0–R8) for pull-up/pull-down customization on CS, SCL, SDA, and INT lines - enabling flexible bus topology setup.

FAQ

Does STEVAL-MKI215V1 require external firmware or drivers to operate?

No. The board itself is passive and requires no firmware. It functions as a breakout interface only. Full operation depends on host platform firmware (e.g., STM32 HAL libraries on STEVAL-MKI109V3) and MEMS Studio software, which provides prebuilt drivers and register configuration tools for the LSM6DSO32.

Can STEVAL-MKI215V1 be used standalone without a motherboard?

No. It lacks power regulation, microcontroller, USB interface, or debug circuitry. It must be inserted into a compatible carrier such as STEVAL-MKI109V3, STEVAL-MKI109D, or X-NUCLEO-IKS4A1 to provide power, communication bridging, and host connectivity.

What is the purpose of the OCS pin on STEVAL-MKI215V1?

OCS (Output Clock Selection) is a dedicated LSM6DSO32 pin routed unaltered on the board. It selects internal oscillator source (26 MHz or 52 MHz) for sensor output data rate timing and is required for precise synchronization in time-critical motion fusion algorithms.

Are the JP1 and JP2 headers on STEVAL-MKI215V1 used for programming or debugging?

No. JP1 and JP2 are 12-pin male headers matching the DIL24 socket footprint - they serve purely as mechanical and electrical mating interfaces. No programming signals (SWD, UART, etc.) are routed through them; all host control occurs via the carrier board's MCU interface.
