Hello I fast browse your thread, but don't find any info how pic (32MX795F512 in demo board. Same chip in production version?) firmware updates are handled?
If your firmware have bugs/improvements how installed boards are updated? Can it done through CAN bus chained board?
Have you released pic sources yet?
PIC 32MX7xx have ethernet. Have future boards ethernet socket? (maybe somebody develop standalone firmware to avoid raspi..?)
When you plan release BOM? BOM and PIC firmware(/source) are needed bare PCB order customers..
BOM, firmware and board designs will be released when project is done and he is in production.
Also, i dont believe it to be interesting to reinvent the wheel. Raspberry Pi is a perfectly cheap solution for running CGminer from out of. It will be much more expensive to have this on each and every board..
