Firmware was not changed or altered. It still shows the firmware that you installed on Jan 21, 2016 with your name as author, before you shipped.

I will check the resistor to make sure it is making a connection. I just soldered it straight to the T0. Still got an over temp.

I think I just figured it out. I’m using 1/4W resistors, so I put a 200k Ohm on and it worked. Now testing all my motors, board is active.

Thanks for all your help everyone.
