We don’t have much personal experience with DOF hardware, but this Arduino library which reads and compensates for three-axis magnetometer and accelerometer data looks very impressive.

The controller consists of a battery-powered Arduino MKR1000 with WiFi and an MPU6050 accelerometer. Held in the hand, the controller streams accelerometer data to an external PC, capturing the ...

This IMU combines an accelerometer ... the Nano 33 BLE Rev2 offers a clear path to upgrade to the Nano 33 BLE Sense Rev2. The release of the Arduino Nano 33 BLE Rev2 is a clear indication of ...

With it, via I2C, I could add an Arduino Pro Mini, and an I2C Oled Display and make a watch capable of having all this information, plus a pedometer (by analysing accelerometer data). Cool enough ...
