Quickstart version of PTP2 (3.5" touchscreen adapter)

The original PTP and PTP2 are for Propeller Platform.
Since Quickstart came out, I thought I'd make a PTP2 "mezzanine" for Quickstart.

The prototype works just fine:

The good thing about it is that it just plugs in and runs off of USB power.
So, it's easy to use and it's a very small package.

Perhaps one not so good thing is that it covers up all the I/O.
So, if you wanted to connect more things to it, it might be tough...

If anybody sees a way to make it better, please let me know.
I'm kinda on the fence about getting a batch made...

    Another very cool board.

    We could still run wires to the holes in front of the QuickStart's header right?

    Another option would be to add headers to the bottom of the QuickStart board and use a "basement" board to access additional I/O pins.

    Thanks Duane. That's a very good point. Somehow I forgot about those extra holes...
    Coming in from the bottom still gives access to those, as you said.

    Well, we sold this first one already, so maybe there is some demand...

    Yes, another cool board! Well done!

    Any chance of adding an SD card and a LIPO power connection?

    With those additions, you'd have a pretty powerful little handheld sandwich.

    Rayman-

    Would it also be possible to extend the footprint of the PTP2 mezzanine board so an additional downward facing 40-pin connector could be placed just outside the current one, wired in parallel? One would be used to plug into the Quickstart board. The second would allow access to all P-pins. I suppose it could be populated with an upward or downward facing header provided it sat far enough out from the touch screen to be accessible. Just a thought.

    Nice board and I really like this move to USB power.

    Did actually decide to sell these boards... So they are up for sale now here: http://www.rayslogic.com/Propeller/Products/PTP2/PTP2.htm

    pgbpsu, sorry, I guess I didn't reply back... Maybe I should have made the board bigger, but decided to keep the same design (same size as Quickstart) rather than take a chance on doing something wrong for the production run.

    mindrobots, see now I forgot to reply to you too... There is the second 40-pin connector... Maybe somebody can make something that connects to that...

    Or, one can maybe use stackable headers to put another board on somehow...
