Product details
Overview
STEVAL-MKI178V1 from STMicroelectronics is a DIL24 socket adapter board designed to evaluate the LSM6DSL 6-axis inertial measurement unit (IMU), providing full pin access, on-board decoupling capacitors, and direct compatibility with STEVAL-MKI109V2/V3 motherboards for rapid prototyping in motion-sensing applications.
For engineers reviewing the STEVAL-MKI178V1 datasheet, STEVAL-MKI178V1 pinout, STEVAL-MKI178V1 application, or STEVAL-MKI178V1 equivalent, this adapter enables immediate sensor integration testing via standard DIL24 footprint, GUI-based configuration using Unico software, and firmware-level validation of I²C/SPI communication, interrupt handling, and power supply sequencing.
Technical Context
The board implements a passive breakout interface between the LSM6DSL LGA-16 package and a 24-pin dual-in-line socket, preserving all signal integrity paths including VDD/VDDIO separation, dedicated INT1/INT2 interrupt outputs, configurable CS/OCS pins for SPI mode selection, and SDO routing for multi-device addressing.
It supports both I²C (SCL/SDA) and 4-wire SPI (SCL/SDA/SDO/CS) protocols, includes 100 nF ceramic decoupling on VDD, and routes all 16 LSM6DSL signals-including RES (reset) and NC-without signal conditioning or level translation, maintaining native voltage domains (1.71–3.6 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Form Factor | DIL24 socket adapter board - enables plug-and-play evaluation without soldering or custom PCB design. |
| Target Device | LSM6DSL 6-axis IMU (3-axis gyroscope + 3-axis accelerometer) in LGA-16 (3×3 mm) package. |
| Power Supply | VDD = 1.71–3.6 V; VDDIO = 1.71–3.6 V - independent rails support mixed-voltage host interfacing. |
| Interface Support | Full I²C (400 kHz fast-mode) and 4-wire SPI (up to 10 MHz) - no protocol translation or clock stretching required. |
| Interrupt Outputs | Two dedicated open-drain outputs (INT1, INT2) - configurable for FIFO threshold, motion detection, or tap/double-tap events. |
| Decoupling | Two 100 nF X7R ceramic capacitors on VDD - meets LSM6DSL recommended power supply filtering per datasheet. |

FAQ
Does STEVAL-MKI178V1 include the LSM6DSL sensor IC?
No. The STEVAL-MKI178V1 is a passive adapter board only - it does not include the LSM6DSL IC. Users must supply their own LSM6DSL in LGA-16 package and mount it onto the board's footprint before use with DIL24 sockets or motherboards.
Which motherboards is STEVAL-MKI178V1 compatible with?
It is fully compatible with STEVAL-MKI109V2 and STEVAL-MKI109V3 evaluation motherboards, which feature a 32-bit STM32 microcontroller acting as a USB-to-sensor bridge, enabling real-time data streaming and register configuration via Unico GUI or custom firmware.
Can STEVAL-MKI178V1 be used with other LSM6x-series sensors?
No. The board is specifically laid out for the LSM6DSL pinout and LGA-16 footprint. While LSM6DS33 shares the same package, its pin mapping differs (e.g., RES and NC locations), making it incompatible without hardware modification or signal rerouting.
What software tools support STEVAL-MKI178V1?
ST's Unico GUI is the primary tool - it communicates over USB via the STEVAL-MKI109V2/V3 motherboard to configure registers, visualize real-time accelerometer/gyro data, set interrupt thresholds, and export calibration parameters for embedded firmware integration.
