I'm trying to put together a datalogger that takes accelerometer data, gps, pressure/temp sensors, and some other stuff, and dumps all of it off to an SD card. A couple remote sensors will send additional data to the "base" station.
I can't imagine that I'm the first person to need GPS/accel/wireless(non-wifi)/SD/battery management all on the same board. The pressure/temp and other stuff, I'll add myself. Can anyone point me in the direction of such a beast? My current solution is going to be a 20-30 cm^3 beast - not including the battery - and I'd like to get that down.
