Description
Unit DoF10 is a 10-axis attitude sensing unit that integrates a six-axis inertial sensor, a three-axis magnetometer, and a barometric pressure sensor. It features the low-power BMI270 IMU, the BMM350 three-axis magnetometer, and the SPA06-003 pressure sensor. The BMI270 integrates a 16-bit 3-axis accelerometer and a 16-bit 3-axis gyroscope, with configurable measurement ranges and on-chip motion event detection. The BMM350 uses TMR (tunnel magnetoresistance) technology for three-axis magnetic field measurement, achieving approximately 0.1 μT resolution and excellent temperature stability. The SPA06-003 measures pressure, temperature, and relative altitude.
Unit DoF10 outputs acceleration, angular velocity, temperature, three-axis magnetic field, and pressure data in real time, making it suitable for robot attitude estimation, heading detection, electronic compass, motion tracking, barometric altimetry, floor change detection, drones, and other applications.
