Gravity: BMX160+BMP388 10 DOF Sensor

Introduction The BMX160 9-axis absolute orientation sensor from Bosch Sensortec is an ideal solution for applications that face strict constraints of board space, power consumption and appearance, especially for wearable device like smart watches or augmented reality glasses. This BMX160 sensor is the smallest 9-axis sensor in the industry. It comprises an accelerometer, gyroscope and geomagnetic sensor in a single package, and features less than 1.5mA power consumption. Combined with BSX sensor data fusion software library of Bosch Sensortec, the sensor performance can be further improved. BMP388 is a high performance barometric pressure sensor with compact body, high resolution, and the smallest size in same series. The BMP388 delivers outstanding altitude stabilization in drones, where accurate measurement of barometric pressure provides the essential altitude data for improving flight stability and landing accuracy.

This module is a combination of BMX160 and BMP388 from DFRobot, which is perfectly suitable for using in drone applications to measure height, attitude and orientation. Features
