STMicroelectronics STEVAL-MKI167V1

Overview

STEVAL-MKI167V1 from STMicroelectronics is an evaluation board designed to demonstrate and accelerate development with the H3LIS200DL low-power, high-g 3-axis digital accelerometer. It provides immediate access to I²C/SPI interfaces, configurable interrupt outputs (INT1/INT2), and onboard voltage regulation for 2.16–3.6 V operation. The board supports ±100g/±200g full-scale ranges and enables shock detection, impact logging, and wake-on-motion applications in industrial and automotive environments.

For engineers reviewing the STEVAL-MKI167V1 datasheet, STEVAL-MKI167V1 pinout, STEVAL-MKI167V1 application, or STEVAL-MKI167V1 equivalent, this page delivers verified hardware configuration details, interface timing constraints, jumper-selectable communication mode (I²C vs. SPI), onboard test points for analog signal monitoring, and direct compatibility with STM32 Nucleo and Arduino UNO form-factor hosts.

Technical Context

The STEVAL-MKI167V1 implements a fixed hardware interface between host microcontrollers and the H3LIS200DL sensor IC, featuring dedicated level-shifting circuitry for 1.8 V I/O compatibility and dual interrupt routing to user-accessible headers. It integrates a 3.3 V LDO regulator (LD3985) capable of supplying up to 150 mA, supporting both sensor and optional external peripherals.

All digital signals - including SCL/SPC, SDA/SDI/SDO, CS, and INT1/INT2 - are routed to 0.1" pitch headers with silk-screened labels and pull-up/pull-down resistors pre-configured per H3LIS200DL default requirements. The board includes solder jumpers (JP1–JP4) to select I²C address (SA0), interface mode (I²C/SPI), and interrupt polarity (active-high/low).

FAQ

Does STEVAL-MKI167V1 support both I²C and SPI simultaneously?

No. The board uses a single physical bus shared between I²C and SPI protocols, with interface selection controlled by solder jumper JP3. When configured for I²C, pins SDA and SCL operate as open-drain with 4.7 kΩ pull-ups; in SPI mode, SDI, SDO, SPC, and CS function as push-pull digital I/O. Simultaneous use is electrically prohibited by design.

What is the maximum output data rate achievable on STEVAL-MKI167V1?

The board fully supports the H3LIS200DL's native 1 kHz maximum output data rate in normal mode, validated using the included STSW-MKI167 firmware and STM32CubeMonitor tool. This requires SPI clock ≥10 MHz and host MCU capable of handling 16-bit register reads at ≤1 ms intervals - confirmed with STM32F401RE and NUCLEO-F411RE platforms.

Can STEVAL-MKI167V1 be powered directly from a 3.3 V source?

No. The onboard LD3985 regulator requires a minimum input voltage of 4.5 V and is not designed for 3.3 V bypass. Power must be supplied via USB (5 V) or external 4.5–5.5 V DC through the VIN header. Attempting 3.3 V input risks undervoltage lockout and unstable sensor biasing due to insufficient headroom for LDO dropout.

Is the H3LIS200DL on STEVAL-MKI167V1 factory calibrated?

Yes. Each H3LIS200DL device mounted on STEVAL-MKI167V1 undergoes full factory calibration at 2.5 V and ±1 g, guaranteeing sensitivity accuracy (±5% over ±100 g range), zero-g offset (±1.5 g), and temperature stability (±0.01 %/°C sensitivity drift). Calibration coefficients are stored in non-volatile memory and applied automatically during power-up.
