Product details
Overview
STEVAL-MKI103V1 from STMicroelectronics is a MEMS demonstration board built around the LPY410AL dual-axis analog gyroscope (±100 dps pitch/yaw sensing), featuring switchable analog and digital working modes, ST7 microcontroller-based sensor-to-PC interface, and USB-powered operation with GUI support.
For engineers reviewing the STEVAL-MKI103V1 datasheet, STEVAL-MKI103V1 pinout, STEVAL-MKI103V1 application, or STEVAL-MKI103V1 equivalent, this board enables rapid evaluation of LPY410AL's analog output linearity, digital acquisition timing, mode-switching behavior, and host PC integration via ST-provided GUI software.
Technical Context
The board implements two mutually exclusive operational modes: Analog Working Mode (AWM), where the ST7 MCU is disabled and raw analog outputs (pitch/yaw) are routed directly to header pins; and Digital Working Mode (DWM), where the ST7 acquires sensor data via internal ADC, formats it for USB transmission, and exposes control registers for configuration.
Mode selection is hardware-controlled via jumper JP1 and power-up default behavior; AWM activates automatically on power application, while DWM requires JP1 closure and firmware initialization. The board includes dedicated 3.3 V LDO regulation, OSCIN/OSCOUT crystal interface for MCU clock, and test points for ICCSEL, ICCCLK, and ICCDATA signals used in DWM.

FAQ
What are the two operational modes of the STEVAL-MKI103V1, and how are they selected?
The board supports Analog Working Mode (AWM) and Digital Working Mode (DWM). AWM is active by default on power-up and routes LPY410AL's analog outputs directly to header pins; DWM requires closing jumper JP1 and running ST's GUI software to enable ST7-based digital acquisition and USB communication. Mode selection is hardware-gated and mutually exclusive.
Does the STEVAL-MKI103V1 require external programming tools to operate in Digital Working Mode?
No external programmer is required. The ST7 microcontroller is pre-flashed with firmware supporting USB CDC communication and sensor interface logic. Users only need to install ST's provided GUI application on a Windows PC and connect via USB to begin real-time data acquisition and register control in DWM.
Can the analog outputs of the LPY410AL be accessed simultaneously with the digital interface?
No. The analog and digital modes are hardware-isolated and mutually exclusive. In AWM, the ST7 is powered down and analog outputs appear on headers J2–J3; in DWM, the ST7 is active and drives the USB interface - analog outputs are disconnected from external pins and only accessible internally for ADC sampling.
Is the STEVAL-MKI103V1 still in active production, and what is its lifecycle status?
Yes, STEVAL-MKI103V1 remains available through STMicroelectronics' authorized distribution channels and Aetrix Electronics. While the LPY410AL sensor itself has been superseded, this evaluation board is maintained for legacy design support, academic use, and backward-compatible motion sensing validation per ST's product longevity policy for evaluation kits.
