Bosch BMI088 Inertial Measurement Units

Bosch’s BMI088 features high vibration suppression for drone and robotic applications.

Bosch Sensortec’s BMI088 is a high-performance 6-axis inertial sensor consisting of a 16-bit digital, triaxial, ±24 g accelerometer and a 16-bit digital, triaxial, ±2000°/s gyroscope. BMI088 allows highly accurate measurement of orientation and detection of motion along three orthogonal axes. With high vibration robustness and a small footprint of 3 mm x 4.5 mm x 0.95 mm, BMI088 is unique in the class of high-performance IMUs used in harsh environments, such as those in drones and robotics applications. BMI088 is specifically designed to effectively suppress vibrations that could occur due to resonances on the PCB or the structure of the total system. Apart from high vibration robustness, the excellent temperature stability of BMI088 helps reduce the design effort and costs on a system level.
