These aren't full computers, but they're more powerful microcontrollers than Arduinos and cheap (less than $3) and have support 802.11n on 2.4 GHz with all modes (ad-hoc, master, client). Not sure if they support multiple SSIDs at the same time. Power usage is about 0.6 watts when maxing out wifi transmit power. | |||
= Omega2 single board computer = | |||
* Actually $5 including tax and shipping | |||
* Single 2.4 GHz radio with on-board antenna and u.fl connector | |||
* Has USB and ethernet but no ethernet transformer or plug. | |||
* Power usage: Unknown but probably small. | |||
* Runs OpenWRT | |||
* You can order as many as you want now | |||
* Doesn't ship until November (estimated) | |||
= Raspberry PI zero = | |||
* Not actually $5 since they can't keep up with demand (more like $15 on ebay) | |||
* No wifi, no ethernet. | |||
* A three-port USB hub with built-in ethernet and micro-usb cable is ~$3 on aliexpress | |||
* Single micro-usb port. You can get $3 | |||
* Power usage: Unknown but probably small. | |||
* Runs Debian (well "raspbian") | |||
= The Next Thing Co. C.H.I.P. single board "$9 computer" = | |||
* Power usage: Unknown but probably small. | |||
* Actually costs $12 in CA with tax and shipping if you order the maximum of 5 units at a time | |||
* Single 2.4 GHz wifi with no external antenna plug (not even u.fl) | |||
* Single USB port | |||
* Runs Debian | |||
[[User:Juul|Juul]] likes it. Easy to flash, easy to use and runs debian stably. Its wifi chipset only supports two wifi SSIDs but both master and ad-hoc mode is supported (probably client too but I didn't check). This means that we can have them meshing (ad-hoc) and have client peoplesopen.net but no private SSID. | |||
= Nexx WT3020F - Very cheap home node ($12.50) = | |||
