Inertial Measurement Unit: BMI088
High performance. Optimized for drones and robots.
BMI088
IMU combining accelerometer and gyroscope
The BMI088 is a high-performance 6-axis inertial sensor that allows for highly accurate measurement of orientation and detection of motion along three orthogonal axes. Consisting of a 16-bit digital, triaxial accelerometer and a 16-bit digital, triaxial gyroscope, the BMI088 is unique in the class of high-performance IMUs used in harsh environments such as those ones in drones and robotics applications. Apart from its high vibration robustness, the excellent temperature stability of BMI088 helps reducing design efforts and costs on a system level.
