Product function
Micro Gyroscope Assembly is a compact, high-precision unit integrating a three-axis MEMS gyroscope, temperature sensor, and signal processing system. It outputs compensated two- or three-axis angular rate data via RS-422, ensuring stable and accurate performance.
Designed as a full replacement for the STIM210, it is ideal for UAVs, robotics, inertial navigation, and stabilized platforms.
