Brief Introduction
IMU388 is a high performance tactical grade MEMS Inertial Measurement Unit, which enjoys high accuracy: MEMS gyroscope is 0.6°/h bias instability (Allan) and MEMS accelerometer is 30µg bias instability (Allan), and its MEMS gyroscope range can be optional in ±250°/s~ ±4000°/s, the accelerometer range is ±40g, and it can output precise 3-axis outputs of angular rate and 3-axis acceleration data.
IMU388 adopts latest MEMS technology and advanced MEMS components, and it has been produced in bulk, which reduces the cost deeply. IMU388 can output precise measurement data in harsh environment, and it has been widely applied in unmanned aircraft, unmanned surface vessel, platform stabilization, industrial robotics, etc., and IMU388 is easily integrated into the variety of architectures that these applications present. The extremely small size, light weight, and low power make the IMU388 ideal for most applications.
