Hi Seeed Community!
I am thinking about buying Grove - 3-Axis Digitial Compass v2.0 for my Pi Zero W.
I have 2 questions regarding this sensor:
Does the Pi have to be on a flat surface for this sensor to work? Or this works as mobile phones do in any device position? The reason why I am asking is because the device I am building will always be carried around by the user.
Does it need to be calibrated? The reason why I ask is because in the sensor page only speaks on how to calibrate it for Arduino and not for the Pi.
Thank you so much for your help!
