10 DOF IMU Sensor (D), Inertial Measurement Unit, ICM20948 Onboard, Lower Power Consumption, High Precision
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.
- Comparing 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
- You can get the 10 DOF data through I2C interface
