BusPirate v4.1 HW proposal

September 19, 2011, 07:43:33 pm

Hi,

I have checked BPv4 schematics and lot of pins are unused.
List of unconnected/unused pins:
RE0, RE1, RE2, RE3, RF1, RF0
RG6, RG7, RG8, RG9, RB3, RB4
RB11, RB12, RB13

Could it be possible to route those unused pins to a Pin Strip Header (like the ICSP one) for extension purpose ?
Such GPIO/pins could be used to program/read parallel RAM/Flash memory or other parallel peripheral ....

Best Regards

In a later version we may route a few extras, but the PCB is super crowded already and I don't think it will be possible to do many on a 2 sides PCB.
