Drone Flight Controller Inertial Measurement Unit Stim300 with Low Noise
The MEMS inertial measurement unit consists of a three-axis gyroscope, three-axis accelerometer, three-axis inclination angle sensor, temperature sensor, signal processing board, and necessary software. It measures three-axis angular rate, three-axis acceleration, and three-axis inclination angle of a carrier, outputting compensated data (including temperature, installation misalignment, and nonlinear compensation) via RS-422 serial port.
