Strong adaptability
High performance
Full-temp calibration
This high-performance IMU integrates a triaxial gyroscope and accelerometer for precise angular rate and acceleration measurement. It features full-temperature calibration to ensure stability and reliability across varied environments, and delivers compensated data - corrected for temperature, misalignment, and nonlinearity - via high-precision SPI.
