Hi!
I'd like to share with my next attempts to integrate the following devices via PSP-SIO:
Accelerometer 3Axis: http://www.sparkfun.com/commerce/produc ... cts_id=410
that should be powerd with PSP low voltage
Cellular Quad Band Module:

Dimensions of UMD, could be integrated via PSP-SIO, too
Any experiences by anybody on these sort of devices?
