A note to DIYers
This board is so far one of the hardest for DIY. Lots of thin traces with spacings of often just 8mils. In addition, several wire bridges (for single-sided boards) / top side traces (for double-sided boards) are very close to IC pads. These facts make this particular board a challenge for people who are not regularly etching PCBs at home. For details, go ask on the PHCC forum.
