Hi Steven,
This project is still moving pretty slowly.
I will be sending a revB proto to Dave Schmidt to do some testing for me
especially as it relates to ATDPro. I still have not sent in the Rev C design files
but that should be within a week or two. I am trying to verify the signal integrity
of the Rev B boards before I submit the Rev C design. I am hoping that RevC
will be perfect and its design files will become the production version of the board.
There is still a fair amount of firmware to be written to make the product ready
to ship. I believe this project will get finished but it is really starting to drag time-wise I know.
Rev C PCB has some changes that will help make the board easier and slightly less expensive
to manufacture. I also hope the changes will result is a lower percentage of dead PCBs from
some the CFFA 2 runs. Sometimes I had 10% reject PCBs. Ouch!! I think the main culprit
was the 6mil spacing between copper. I am trying to use 8mil most of the time and 9mil where I can.
