Wish I had 2 modules
I think this project could be done in 1 or 2 evenings I have most the parts already.
What I would do is build a mini back panel it would accept 2 modules,12 volts and USB.
It would take 12 volts in using a 6 lead PCI-e connector like many other projects use.
The mini back panel would regulate 12 volts to 3 volts for input to the modules or use 3.3 volts form the power supply.
The mini back panel would have a DIP version of the PIC16LF1459 and a small amount of glue logic to connect the report_n & report_p signals to the PIC.
The only other thing would be USB connector to connect a host for running cgminer.
The hardest part for me would be the 3 volts for supplying to the modules.
