CRM100 and CRM200 form a series of chip-level silicon MEMS gyroscopes from Silicon Sensing, offering low-noise angular rate measurements in a small surface-mounted package. The CRM100 mounts flat on a board, whereas the CRM200 version is mounted on its side, which when combined, enables the three degrees of freedom measurements (roll, pitch and yaw) to be made with a single board.
