Leo Store - Silicon Sensing - CMS390 (Orthogonal) MEMS Combi-Sensor 1

CMS390 (Orthogonal) MEMS Combi-Sensor

Industry-leading orthogonal combi-sensor


CMS390 combi-sensor is a combined single-axis gyro and dual-axis low-g accelerometer. The unit features user-selectable dynamic range and bandwidth, with a digital SPI output. The CMS390 is mounted on its side (orthogonal), combined with the CMS300 enables all axes to be measured using a single board (PCBA).
