We have opened public Beta version sale in China for RMB$148(as US$24)www.leiphone.com/d-wrtnode-opening.html, and closed today as two month later. Our hundreds of trial users all over the china help us a lot in RESTful api, a better uboot, and more. We are satisfactory with the board untill now.
We have donated 20 boards for the BattleMesh V7 http://battlemesh.org/BattleMeshV7#Donated_OpenHardware_-_WRTnode.
And the Schematic is: content/uploads/2014/05/WRTnode_sch_v01.pdf , and we will give all the BOMlist and PCBlayout soon.
And for the source other than openwrt.org provides, we opened on github.com/WRTnode.
Maybe it will be sold publicly at the ends of July.
