What's the difference between the Freematics OBD II adapter and the Arduino OBD II adapter? The source for the Arduino one looks way, way more useful to me.
Is it just that the Freematics one hosts its own Uno board? Is there any way to use the Arduino code on the Freematics adapter, or plug in the leadout from Freematics into another Uno and pretend it's the Ardiuno version?
My adapter is pretty useless at the moment, I can't get it to do a few things I'd really want.
