Product details

Overview

STEVAL-MKI034V1 from STMicroelectronics is a MEMS analog-output demonstration board built around the LPR510AL dual-axis (pitch and roll) gyroscope, supporting ±100°/s and ±400°/s full-scale ranges, with selectable analog (AWM) or digital (DWM) operation modes, and featuring an integrated ST7 microcontroller for PC interface via USB.

For engineers reviewing the STEVAL-MKI034V1 datasheet, STEVAL-MKI034V1 pinout, STEVAL-MKI034V1 application, or STEVAL-MKI034V1 equivalent, this board enables rapid evaluation of gyroscopic sensing in motion control, stabilization, and tilt-sensing systems - with direct analog output access or GUI-driven digital acquisition.

Technical Context

The board implements two mutually exclusive operational modes: Analog Working Mode (AWM), where the ST7 MCU is disabled and raw analog outputs from the LPR510AL are routed to header pins; and Digital Working Mode (DWM), where the ST7 acquires sensor data via dedicated interface lines (ICCDATA, ICCCLK, ICCSEL), processes it, and communicates with PC software via USB-serial bridge.

Signal conditioning includes on-board voltage regulation (6DD/6SS rails), oscillator circuitry (OSCIN/OSCOUT), configurable filter paths (FLTIN8/FLTOUT8, FLTIN9/FLTOUT9), reference voltage generation (6REF), and LED indicators for power and mode status - all supporting both evaluation and prototyping-level integration.

Key Specifications

Parameter	Value and Actual Design Meaning
Sensor Core	LPR510AL dual-axis MEMS gyroscope for pitch/roll angular rate measurement
Full-Scale Range	Configurable ±100°/s or ±400°/s - determines resolution and dynamic range for motion capture
Output Modes	Analog Working Mode (AWM): direct analog voltage outputs; Digital Working Mode (DWM): digitized data via ST7 MCU and USB
Interface MCU	ST7 microcontroller acting as sensor-to-PC bridge, enabling GUI-based visualization and pin control
Power Supply	USB-powered (5 V) or external supply connector - supports immediate plug-and-play without external regulators
Filtering	Dedicated analog filter paths (FLTIN8/FLTOUT8, FLTIN9/FLTOUT9) for noise suppression before ADC or output stages

Manufacturer

STMicroelectronics is a global semiconductor leader headquartered in Geneva, designing and manufacturing microcontrollers, sensors, power ICs, and analog/mixed-signal devices for industrial, automotive, and consumer applications.

This board belongs to ST's STEVAL (ST Evaluation) platform family, engineered specifically to accelerate validation and integration of ST's MEMS motion sensors into real-world systems with minimal hardware setup.

FAQ

What are the two operational modes of the STEVAL-MKI034V1?

The board operates in Analog Working Mode (AWM), where the ST7 MCU is powered down and raw analog outputs from the LPR510AL gyroscope are accessible on header pins; or Digital Working Mode (DWM), where the ST7 MCU is active, digitizing sensor data and communicating with PC software via USB. Mode selection is determined by power-up configuration and jumper settings.

Does the STEVAL-MKI034V1 require external programming hardware?

No - the board does not require external programmers. The ST7 microcontroller is preloaded with firmware enabling immediate USB communication and GUI interaction. Firmware updates or custom code deployment would require an ST7-compatible debugger, but out-of-box functionality is fully self-contained with only a USB cable needed.

Can the LPR510AL sensor be replaced with another ST gyroscope on this board?

No - the STEVAL-MKI034V1 is specifically designed for the LPR510AL and its pinout, biasing, and signal routing are not compatible with other ST gyroscopes (e.g., LYPR520AL or LPY550AL). Mechanical, electrical, and interface constraints prevent substitution without PCB redesign and firmware adaptation.

Is the STEVAL-MKI034V1 still supported for new designs?

The board is marked "Obsolete Product(s)" in its official documentation (Doc ID 18358 Rev 1, Jan 2011), indicating ST no longer recommends it for new designs. However, Aetrix Electronics maintains limited inventory for legacy system maintenance, repair, and educational use where functional equivalence and historical compatibility are required.
