Just received my TL-WR703N this is awesome for the price don't know if I will us it or PI to run my k16's.
A few of my saved links as to why this unit is so interesting. I'm sure I also saw that someone completely reversed the PCB as well, but can't find it now.
One of my ideas that I hope to explore later: use it as QuadCopter engine so that via Wifi and USB camera, you can control flight with your Android tablet. Even if it meant removing the AR9331 and implementing a dedicated PCB controller with Gyros etc.
But that's a whole 'nother topic I don't have time for right now.
