We have not been working on this but normally Carambola 2 module promises 0.5W power consumption (http://www.8devices.com/carambola-2). In general AR9331 is very power efficient (http://wiki.openwrt.org/toh/tp-link/tl-wr703n). WeIO has some extra components (USB hub and MCU), but generally should not be very different in the terms of power consumption. It is powered by 5V USB, or via external power supply (has a regulator circuit on board). In this sense any external battery, like the ones used as extra batteries for mobile phones and tables, should work without problems. But there is no battery management circuit in the sense that we can measure battery status at first revision of WeIO. We will be looking at more industrial solutions for the second revision and maybe add some missing features. > The AR9331 uses the Ath9K wifi driver? Yes, and this is probably the best Linux WiFi driver. It is very powerful, has even opened FW part and can support virtual interfaces - i.e. you can have simultaneous interface in AP and STA mode (tested and working with WeIO). > I'm thinking about ease of sticking it in a tree with a solar panel. I do not have experience with this, but basically any supply between 5V and 15V will be OK for powering the board. I am planning to do some measurements on the new batch that arrived a few days ago, and I can present you exact consumption figures.
