Hello Ken,

I don't think i'd ever get this done if I try to make everyone happy ;-)  As long is I haven't submitted the PCB's to have them made I can still (relatively easy) make changes which will enable the module to be flexible.  Since the start of this i've already picked up a few things that will help.  Running the module at 3.3v instead of 5v will only require a few parts to be swapped out.  Since I had been looking at this as a kit then either set of parts could go in so the cost should be a wash for 3.3v vs 5v.  The only concern was for people who had circuits which either feed +5v or expect +5v from pin 37.  That would not be the case with the 3.3v regulator on board.  I think I am just going to leave it connected as is since the number of people who it would even be an issue for is probably pretty small and they could work around it.  A simple fix for them would be to just get a cheap 40-pin dual leaf socket and bend up pin 37 and pin 40.  They could plug that socket into their board and the module into that.  From there power can be connected to either pin.  It avoids messing with the module itself.

As of this morning I think I pretty much have the final board wrapped up and like the way it looks.  I'm going to let it sit a day then go back over the board for a final check before sending them off.  I think this will be really cool and a useful little kit!

Robert
