9 DoF Razor IMU M0

9 DoF Razor M0: a versatile and reprogrammable IMU

The 9 DoF Razor IMU M0 by SparkFun was created by combining an SAMD21 microprocessor equipped with a pre-installed firmware with an IMU with 3 sensors:

• 1 x 3-axis accelerometer
• 1 x 3-axis gyroscope
• 1 x 3-axis magnetometer

You can use the Razor M0 module with its original firmware, or you can reprogram it in Arduino via a USB connection. The microprocessor offers full hardware compatibility with Arduino and Arduino Zero.

How do I use my 9 DoF Razor IMU M0?

With the 9 DoF Razor IMU M0, you benefit from an ultra-precise navigation instrument, including calculation of Euler angles and quaternions. You can also use it to create a pedometer.
