Hammerhead PI-1 PCB Rev B

[wbblair3]

I have a PI-1 Rev B PCB dated 9 Sep 02 and all of the parts required to populate it. Are there sufficient improvements in the latest PCB revision and Hammerhead design to merit buying the latest PCB and any parts that may have changed from this older version?

Sorry for the slow reply... I think I mainly simplified the design in Rev C. The audio stage is slightly different. I suspect that with very little effort, you could build the Rev C schematic on the Rev B PCB. So, no, you don't really need a new PCB.

OK, I was just wondering if there were any problem fixes or performance enhancements in the later design. I'll just build what I already have then.

Thanks.
