Description
Unit DoF6 is a six-axis inertial sensor unit built around the low-power BMI270 IMU. The BMI270 integrates a 16-bit 3-axis accelerometer and a 16-bit 3-axis gyroscope, with configurable measurement ranges, on-chip motion detection, and fast startup. Data is transmitted over I2C, enabling real-time acquisition of acceleration, angular velocity, and temperature for motion-sensing applications such as robot attitude sensing, motion detection, wearables, gimbal control, and human-machine interaction.
