The issue is ExpressPCB is very expensive for solder mask in small
quantities. The setup fee is $233 so you have to order a lot of
boards to cover this cost. The board needs to be larger so this cost
would increase. Someone with PCB layout software needs to layout the
board in a larger size with standard PCB output files. This larger
size would also allow DIP versions of the DACs to be added so SMT
could be avoided. My layout could be used as a starting base. I know
there are people on this list that have PCB layout skills, software
and experience.
This project will only move forward if others volunteer. I've
contributed all I can.
