I've got an EM406 and was wondering if there's a way to put it into sleep or some sort of powersave mode. I've got an app that will be running on an arduino that only needs power when in an actively "running" mode. The rest of the time, i need the arduino to stay running to monitor some low level activity, but i don't need or want the GPS (and some other peripherals) to be on and consuming battery power.
I looked here: http://www.sparkfun.com/datasheets/GPS/ ... Manual.PDF, but it seems limited in the information it gives and i didn't find anything.
I'm sure i could do this with a relay, but thought there might be a better way.
