Gravity: BMX160+BMP388 10 DOF Sensor

A 10-DOF (degrees of freedom) sensor module combining the Bosch BMX160 9-axis sensor with a BMP388 barometric pressure sensor on a single DFRobot Gravity-compatible board. Measures acceleration, angular velocity, geomagnetic orientation, barometric pressure, and temperature — ideal for drones, robotics, and wearable devices.

The BMX160 is the smallest 9-axis sensor in its class, drawing less than 1.5 mA. The BMP388 delivers high-resolution altitude data for precise flight stabilisation and landing accuracy.
