I thought I would ask around here because there’s a good possibility that other people have been thinking about these issues also, although I didn’t find a thread about it, maybe because we’re all waiting for it to be released…
Can the battery be directly replaced with 3 or 4 Lithium Iron Sulfide batteries in series? Or can a single Lithium Iron Phosphate battery be a direct replacement? I can’t tell from the image whether a 3.3V regulator is used and what the minimum and maximum dropouts are.
Can the Electron and/or GPS unit power down into sleep mode? I would like to power down most of the time to conserve battery life, then send an email or text message once per day, or maybe on command by SMS. Should the GPS unit power input connect to a P-MOSFET switch that is controlled by a pin?
Also, how is the reception? Will the Asset Tracker receive GPS and transmit SMS through the walls of a building?
And do I need to pre-order early to get shipping at end of January 2016?
Answers to any questions would be greatly appreciated.
