Product details
Overview
STEVAL-MKI170V1 from STMicroelectronics is an evaluation board for the IIS328DQ ultralow-power 3-axis digital accelerometer, designed to accelerate development of industrial motion-sensing applications. It supports ±2g/±4g/±8g full-scale ranges, SPI/I²C interfaces, 16-bit output resolution, dual programmable interrupts, and operates from -40°C to +105°C with supply voltage down to 2.16 V.
For engineers reviewing the STEVAL-MKI170V1 datasheet, STEVAL-MKI170V1 pinout, STEVAL-MKI170V1 application, or STEVAL-MKI170V1 equivalent, this board enables rapid validation of inertial wake-up, tilt measurement, vibration logging, and intelligent power-saving functions in embedded industrial systems using the IIS328DQ sensor.
Technical Context
The STEVAL-MKI170V1 implements a complete hardware interface to the IIS328DQ QFPN-24L accelerometer, providing direct access to all 24 pins via solderable test points and standard 0.1" headers. It includes decoupling (10 µF + 100 nF) on both VDD and VDD_IO rails, configurable CS/SCL/SDA/SDO/INT1/INT2 routing, and jumper-selectable I²C address (SA0 tied high/low) and interface mode (SPI vs I²C).
Board-level design supports factory-calibrated operation out-of-box: VDD_IO is independently regulated to 1.8 V for low-voltage I/O compatibility, while VDD accepts 2.16–3.6 V to match the sensor's core supply range. The layout maintains signal integrity for 10 MHz SPI and 400 kHz I²C fast-mode timing, per DS10757 Rev 4 specifications.

FAQ
Does STEVAL-MKI170V1 support both SPI and I²C simultaneously?
No - the board routes the shared SCL/SPC and SDA/SDI/SDO pins to a single header, and interface selection is determined by the CS pin state per IIS328DQ specification: CS = 1 enables I²C; CS = 0 enables SPI. Jumper JP1 configures CS logic level, allowing hardware-mode switching between protocols during development.
What is the purpose of the separate VDD and VDD_IO supplies on the board?
VDD powers the sensor's internal measurement chain (MEMS element and analog front-end), while VDD_IO powers only the digital I/O buffers. This separation allows interfacing with 1.8 V microcontrollers even when VDD is set to 3.3 V, ensuring signal-level compatibility and reducing noise coupling into the sensitive analog path.
Can the STEVAL-MKI170V1 be used for calibration verification of the IIS328DQ?
Yes - the board exposes all critical pins (including INT1, INT2, SA0, and reset) and provides unfiltered access to raw sensor outputs via test points. Combined with ST's Unico GUI software and the onboard IIS328DQ's factory-trimmed sensitivity and zero-g offset registers, it enables end-of-line functional validation and temperature drift assessment across -40°C to +105°C.
Is external programming hardware required to configure the IIS328DQ via STEVAL-MKI170V1?
No - the board features a standard 4-pin SWD connector compatible with ST-LINK/V2 or ST-LINK/V3 debug probes. Configuration is performed via ST's X-CUBE-MEMS1 firmware library and Unico GUI, which communicate over USB-to-UART bridge (onboard CP2102N) or directly via SWD, eliminating need for additional programmers beyond standard ST development tools.
