So I just received the new hardware and looking through the hookup guide it says:
Enable (EN) - By default, the EN pin is closed. This jumper is connected to a processor board’s GPIO pin. The processor board can control the ATP’s voltage regulator. Depending on the processor, this may not be connected
Well I looked at the board and did not see a bridge so I measured the resistance and it is open so it is not closed.
The question is when using the ATP board with Teensy should it be closed?
Thanks
