Sorry to sound Dumb Andy, I do not understand what you mean.

Ohm Supplies:
U4,

What type is fitted (the markings on top) and did the backer that came with the kit say anything about U4?

Hi

Its a sharp PC817,

I have just checked some of the voltages and I am getting about 3v from the 5v pins and 1.6v from the 3.3v pins, if that helps any

Hi
