Product Introduction

Inertial Measurement Unit:U6488

The U6488 series IMU are equipped with built - in three - axis gyroscopes and three - axis accelerometers, which are used to measure the three - axis angular rates and three - axis accelerations of the carrier. The data from the gyroscopes and accelerometers, which have undergone error compensation (including temperature compensation, installation misalignment angle compensation, nonlinear compensation, etc.), are output through a serial port according to the agreed communication protocol. They can be used for precise navigation, control, and dynamic measurement of the carrier. This product uses high - precision MEMS inertial devices, featuring small size, strong overload resistance, high reliability, and high hardness, and it is capable of accurately measuring the angular rate and acceleration information of a moving carrier even in harsh environments.

 

The U6488 series includes four models: U6488-B, U6488-C, U6488-D, and U6488-E. The appearance and interface performance of the four models are consistent. Except for U6488-E, all of them are equipped with built - in three - axis magnetometers and digital barometers.
