Product details

Overview

STEVAL-MKI194V1 from STMicroelectronics is a DIL24 socket-compatible adapter board for the LSM6DSR 6-axis IMU, providing full pin access to its 3-axis accelerometer and 3-axis gyroscope, decoupling capacitors on VDD, and direct plug-in capability for rapid prototyping in inertial sensing applications.

For engineers reviewing the STEVAL-MKI194V1 datasheet, STEVAL-MKI194V1 pinout, STEVAL-MKI194V1 application, or STEVAL-MKI194V1 equivalent, this adapter enables immediate integration with STEVAL-MKI109V3/STEVAL-MKI109D host platforms and MEMS Studio GUI for real-time sensor data visualization and firmware validation.

Technical Context

The board implements a passive breakout interface between the LSM6DSR LGA-16 package and a standard 24-pin dual-in-line socket, preserving all digital I/O (I²C/SPI), interrupt (INT1/INT2), and power (VDD/VDDIO/GND) connections without level-shifting or signal conditioning.

It supports both SPI (via CS, SCL/SDO/SDA multiplexed) and I²C (SCL/SDA) communication modes, with pull-up resistors pre-installed on SDA/SCL lines and configurable interrupt routing to host microcontroller GPIOs on compatible evaluation motherboards.

Key Specifications

Parameter	Value and Actual Design Meaning
Form Factor	DIL24 socket adapter - enables mechanical compatibility with legacy breadboard and test fixtures.
Target Device	LSM6DSR 3×3 mm LGA-16 IMU - provides full pin mapping including OCS, OSDO, SDx, SCx, and RES pins.
Power Support	VDD (1.71–3.6 V) and VDDIO (1.71–3.6 V) decoupled with 100 nF ceramic capacitors - ensures stable supply for low-noise sensor operation.
Interface Compatibility	Fully compatible with STEVAL-MKI109V3 and STEVAL-MKI109D host boards - uses STM32F401VE bridge MCU for USB-to-sensor communication.
Compliance	RoHS and WEEE compliant - meets EU environmental directives for commercial and industrial deployment.

FAQ

Does STEVAL-MKI194V1 include an onboard microcontroller?

No. It is a passive adapter board only - no MCU, memory, or firmware. It relies entirely on external host platforms like STEVAL-MKI109V3 or STEVAL-MKI109D for sensor communication, data streaming, and PC interface via USB.

Can STEVAL-MKI194V1 be used standalone without a host evaluation board?

No. It lacks power regulation, USB interface, and processing capability. It must be inserted into a DIL24 socket on a compatible motherboard (e.g., STEVAL-MKI109V3) to function - no independent operation is supported.

What software tools are supported for configuring the LSM6DSR via this adapter?

ST MEMS Studio - a free Windows GUI application - is fully supported. It enables real-time sensor data plotting, register configuration, FIFO control, and embedded algorithm tuning when used with STEVAL-MKI109V3/D host platforms.

Are the interrupt pins (INT1/INT2) routed to accessible test points or headers?

Yes. Both INT1 and INT2 signals are brought out to dedicated pins on JP1 and JP2 headers (pins 4 and 9 on JP1; pins 6 and 7 on JP2), enabling direct connection to host MCU GPIOs or oscilloscope probes for timing analysis and event-triggered debugging.
