Compact BMI088 gyroscope and accelerometer module

Stable motion data for mobile robots

GYROSCOPE · ACCELEROMETER · I²C

This compact module is built around the BMI088 IMU to provide high-precision rotation data and stable acceleration measurements for mobile robots such as autonomous RC cars. The device combines a high-performance gyroscope and low-noise accelerometer as separately optimized sensing elements, maintaining stable output during vibration and sudden movement.
