LMG618 is a highly integrated low-power inertial measurement unit (IMU). It can be used for the precise navigation of carriers. Control and dynamic measurement. This series of products uses high-precision MEMS inertial devices. With high reliability and high accuracy. It can accurately measure the angular velocity and acceleration information of moving carriers in harsh environments.
LMG618 built-in three-axis gyroscope and three-axis accelerometer. For measuring the triaxial angular rate and acceleration of a carrier.
The acceleration measurement range is: ±2g, ±4g, ±8g, ±16g, 32g.
The gyroscope measurement range is: ±125°/s , ±250°/s, ±500°/s, ±1000°/s, ±2000°/s, ±4000°/s.
