Search main.c and setup.c I guess to learn how a digital input pin is initialized. Then make sure that no uart3 is initialized and initialize the two pins as digital...

No. Make progress yourself

Seeing the speed potentiometer to near zero should do a lot breaking. Not in torque mode of course. Don't know if the motors can generate more breaking power then simply...

I only use your FOC firmware so i simply assume that no firmware has better protection and you might want to make your firmware even better with additional mosfet protections.....

You can now download compiled binaries for the V2.0 and V2.1 boards as well as tested Arduino examples on my fork: https://github.com/RoboDurden/Hoverboard-Firmware-Hack-Gen2.x I can only test the PPM rc-receiver Arduino...

Oh sorry, without the @RoboDurden I would not have noticed this new issue. Sorry for that. Will read this issue tomorrow. If this is indeed a new layout, please upload...

Yes, this will be 2.14. But please upload high resolution photos of front and back with cables bent out of view. So all components and circuit lines can be seen.

Do not upload binaries for a different layout. This can kill your board. As this is a new layout, there do not exist any binaries yet. With a new layout...

Great, i now will compile them into a front-back image and add the 2.14 layout to my repo :-)

Yes the pins are very likely different from other layouts. As @pacraf suggested, read some other layout issues here to learn how to trace the pins.
