I am (unfortunately) counting in from the right, so my pin numbering 
is reversed from that shown at

I've got my uBitx Raduino totally unhooked from the wiring harness and the uBitx board,
laying flat on my desk.  Have a USB cable to a laptop to power up the Raduino.
Using a corner mounting hole of the Raduino for ground, I see 4.6 volts on the
first four pins in from the right on the top connector (ENCA, ENCB, FUNCTION, PTT).
The 5'th is ground, so I see 0 volts there.
The 6'th is 5 volts, and I see 4.7 or so because of a diode drop in the Nano.
The 7'th and 8'th are analog pins without pullups, so are pretty much undefined.
