Hi Phil,

I have removed U4 which is the 3.3v regulator chip-internal short as 
pin(out)reads direct short to pin(gnd).

More disturbing is that the pad that pin 2(output)solders to is a dead short 
to earth and this seems to be as a result of the via, which is within the 
silkscreen area for this chip, is connected to the output pad and is 
probably meant to go to the middle pcb layer without being connected to the 
bottom layer gnd plane.  If this is so then I appear to have a dead short on 
all pins/components that access this 3.3v supply.

Am I right in thinking the Penny pcb is at least a 3 layer board, one of 
which carries the 3.3v supply to the various components?

Regards,
