STEVAL-MKI109V2 MEMS Evaluation Motherboard

Parameter

Application

The STEVAL-MKI109V2 is a USB motherboard designed as a universal evaluation platform for STMicroelectronics MEMS sensors. Built around the STM32F103RET6 Arm Cortex-M3 microcontroller, it serves as a bridge between ST MEMS adapter boards and a host PC, enabling rapid evaluation and data acquisition through the USB 2.0 interface. The board features a 24-pin DIL socket compatible with all ST MEMS adapter boards, an on-board 3 V linear regulator, USB DFU firmware upgrade capability, and SWD/JTAG debugging support. When used with ST's Unico graphical user interface or dedicated evaluation software, it provides a convenient environment for configuring, monitoring, and logging data from accelerometers, gyroscopes, magnetometers, pressure sensors, environmental sensors, and other MEMS devices. The STEVAL-MKI109V2 is well suited for sensor characterization, algorithm development, industrial sensing, IoT prototyping, wearable devices, and motion analysis. The product is **Obsolete**, but it continues to support legacy MEMS evaluation platforms and existing development projects. :contentReference[oaicite:0]{index=0}
