STEVAL-MKI109V3 MEMS Evaluation Motherboard

Parameter

Application

The STEVAL-MKI109V3 is a professional MEMS evaluation motherboard designed as a universal development platform for STMicroelectronics MEMS sensor adapter boards. Built around the high-performance STM32F401VE Arm Cortex-M4 microcontroller with DSP and floating-point unit (FPU), it serves as a bridge between ST MEMS sensors and a host PC for high-speed data acquisition and analysis. The board features a 24-pin DIL socket compatible with all ST MEMS adapter boards, software-adjustable sensor supply voltage from 0 V to 3.6 V, integrated voltage and current monitoring circuitry, USB 2.0 full-speed connectivity, USB DFU firmware upgrade capability, and SWD/JTAG debugging support. It works seamlessly with the Unico GUI on Windows, Linux, and macOS to configure sensors, visualize waveforms, capture data, and evaluate operating modes. The STEVAL-MKI109V3 is ideal for characterization and evaluation of accelerometers, gyroscopes, magnetometers, pressure sensors, environmental sensors, vibration monitoring, industrial sensing, wearable devices, IoT product development, and motion analysis. The product is **Obsolete** and has been replaced by the **STEVAL-MKI109D** professional MEMS evaluation motherboard. :contentReference[oaicite:0]{index=0}
