Class-leading Performance in the Smallest, Lightest Package

The 3DM-CV5-IMU is our smallest, lightest, and most power-efficient MicroStrain IMU. This Inertial Measurement Unit is engineered for applications where every gram and millimeter counts, delivering high-performance inertial measurement without compromising on Size, Weight, and Power (SWaP).

As a MEMS-based IMU sensor, the 3DM-CV5-IMU combines a triaxial accelerometer and a triaxial gyroscope in an ultra-compact, factory-calibrated package to provide a reliable stream of high-quality raw motion data. It is the ideal compact IMU for robotics and autonomous navigation, as well as other SWaP-constrained applications that require high performance in a minimal footprint.

End of Life Notice: This product is not recommended for new designs. For all new applications, we recommend the next-generation 3DM-CV7-AR, which offers tactical-grade performance in a similar miniature footprint.
