Is there a forum for all the various Raspberry Pi copycats?
I'm trying to figure out what the best starting point is for a project running off solar for projects such as weather stations.
The alternatives I've found so far are and their drawbacks:
Android devices, Raspberry Pi, Beagleboard, Beaglebone, Pandaboard, mk802
This is what I've found:
Beaglebone: The best I've found. However: "Powering via USB: You should directly power the board from a 5 V power connector instead of the USB OTG port. Power via the USB OTG port might work sometimes (via a USB A to mini B cable), but the BeagleBoard attempts to draw more than 100 mA of current without negotiating any additional current, which violates the USB specification. Therefore, most host software will prevent this to comply with the USB specification. "
Android phones: There are no USB drivers for the USB devices I'm hoping to use, plus I find android a bit limiting and linux would be a lot better.
Raspberry Pi: Again it's possible to run off battery power but I think the Beaglebone is a better starting point.
Spark linux tablet: Possibly a bit expensive. Don't need the touchscreen. Might need some kernel work to get more support for USB devices like software defined radio.
Syneta7-R netbook: Not so simple to convert to linnux? How to charge it from solar, batteries or USB (12v car charger is available).
Here is a comparison table of cheap ARM boards, but sadly it doesn't include the voltages required to drive them: http://socialcompare.com/en/comparison/ ... arm-boards
Running off the standard 3.7v we see in mobile phones would allow us to use cheaply available mobile phone batteries without much hassle. Being able to run off, or charge from USB would allow us to utilise various off the shelf power supplies.
