Overview

10 DOF IMU Sensor (D) features the low-power ICM20948 onboard, it is good at motion monitoring, as well as detecting/measuring the position, height, and temperature.
This tiny module would be helpful for making your own copter or balancing robot, provides great man-machine interaction.

Features

  • ICM20948: low power 3-axis gyroscope, 3-axis accelerometer, and 3-axis compass/magnetometer
    • Internal Digital Motion Processing™ (DMP™) engine, offloads complicate fusion calculation, sensor synchronization, gesture recognition, etc.
    • Compared with MPU9250, it is higher precision, lower power consumption, and more suitable for wearable devices
  • BMP280: barometric pressure sensor
    • Embedded temperature sensor for temperature compensation
    • Compared with BMP180, it is lower power consumption and higher performance
  • You can get the 10 DOF data through the I2C interface
