The pinouts on the -4T are similar, but some of the configuration pins are
Check carefully pins 21-23, which change depending on the model, pins 1-2,
which change (I think) for the -4P model.
Other than that, it's mostly pin-for-pin.
I haven't had a good look over the schematics for the GPSStix - so double
Also, I have just finished designing a (custom, not gumstix) -4T board, and
I have all the components, but haven't been bothered soldering yet. It has
the full box and dice including the USB, serial line drivers, and ESD
protection on all pins exposed to the outside world. I'll let people know
how they do.

I am assuming that the -4T has the same footprint/pinout as the -4H,
which might not be an accurate assumption...
