CMS300 (In-Plane) MEMS Combi-Sensor

A tiny, low-cost, precise Combi-Sensor


CMS300 MEMS combi-sensor combines a single-axis gyro and dual-axis low-g accelerometer. The unit features user-selectable dynamic range and bandwidth, with a digital SPI output. The CMS300 mounts flat on a board, combined enables all axes to be measured using a single board (PCBA)
