Power Olinuxino Maxi from 7.2V battery
« on: December 02, 2012, 06:20:06 PM »
Hello everyone,

I'm trying to come up with a system that would use a 7.2V battery to power an Olinuxino Maxi and an attached modem (connected to UEXT and the 5V supply).

The questions are:

1. Can I hook up 7.2V to the battery input or will it fry everything (the documentation only tells you what happens when you use a standard 3.7V LiPo).

2. Can I put the device to sleep / wake it up using either a GPIO pin or by connecting to the PWR_BUT button somehow? The modem I'm using has a wakeup pin that it switches to "high" when there's an incoming call. I'd like to keep the Olinuxino asleep until there's a call. Is this implemented yet?

3. Will the 5V output still be on while the Olinuxino is asleep? The modem still needs power, even when the Olinuxino sleeps.

Thank you!
Razvan
