Hi.

I've just finished making a PCB for the PicPro 2.5 (using Advanced
PCB/Schematic - Protel for Windows).

The PCB matches Octavio's original schematic, except that it uses a LM317L
instead of the 7808. Furthermore I've changed the V-reg. output capacitors.
It includes the 'production-mode' programming (extra LM317L+trim-pots).

The PCB is single sided, approx. 10*7cm, space for zif-socket and a socket
for in-circuit programming. Smallest clearence/track-width are 15mils,
which should make it easy to make 'at home'.

If anybody wants the PCB+schematic, I'll post it in personal E-mail as soon
as I've etched/tested it (beginning of next week).
