 The goal of this project is to learn as much as possible about the Zsun WiFi card reader and run OpenWrt on it to turn it into an awesome wifi device.
+**UPDATE 2017-09-12** Info about LEDE and USB gadget working \\
 **UPDATE 2016-11-28** Adding some more info about the new PCB revision, thanks to Erik Dorner, who sent me his analysis a long time ago \\
