That makes sense. I figure each active pacsat developer needs at least
one and perhaps two Launchpad boards.

OSHPark expects the panel on Thursday and will likely ship the boards to
me quickly after receiving the panel. I expect the Raspberry Pi boards
early next week. I'd expect each pacsat developer to need three boards
at peak development to implement a two-up-one-down system. If I'm right,
it might make sense to wait until the Raspberry Pi boards arrive. (For
those that might be confused, the Raspberry Pi boards are a convenient
way to develop using the AX5043 and can be jumpered to the LaunchPad...
I've done that before.) (Also, to be clear, the Raspberry Pi boards
require assembly with surface mount components. In particular the AX5043
has a ground pad making the use of a reflow oven beneficial. Admittedly
it could be done with hot air and hand-soldering, too.)

I'll switch to my other computer and pull up what I have. I won't have
any software specifically written for that prototype board I
accidentally sent you as I hadn't assembled one. But I think you'll find
the AX5043 portion to be a lot like the V1.3 board with the addition of
the second antenna connection. Thus, the software written for the V1.3
board should be functional on the prototype board.
