Hello.
We are WRTnode machine team.
We made a open source dev board for OpenWrt named WRTnode,
And today It's released: http://wrtnode.com/
We got all the mt7620n chip IOs pin out for hardware hacking.
And keep it in small size with maximized RAM 64MB with mt7620n.
OpenWrt is a great project, we'll be happy if WRTnode could give more fun to OpenWrt fans.
