This is a compact motion sensing module built around the BMI088 IMU.
The goal of the design is to provide reliable, high-precision rotation data and stable acceleration measurements for mobile robots such as autonomous RC cars.
The BMI088 integrates a high-performance gyroscope and a low-noise accelerometer in separate optimized sensing elements, allowing it to maintain stable output even in environments with vibration or sudden movement.
