Hi, I have a ZBT WG108, it is sold on the internet as an openwrt router with various names.
You can add it among the supported devices?
The hardware specifications are below:
Product number ZBT-WG108 (
but it is renamed by each seller)
Hardware
Cpu MT7621A 880Mhz
Flash:SPI 16MB
Ram：DDR3 256MB
Wifi 2.4Gz mediatek 7603
Wifi 5 Ghz mediatek 7612
Ethernet port provide 5*10/100/1000Mbps Auto-MDI/MDIX
USB 2.0 1 port
SD interface 1
LED PWR,2G,5G,WAN,LAN1,LAN2,LAN3,LAN4
1 RESET button
Power Adapter DC 12V 1A ( if you have a problem of wifi stability change in 2A!! )
I have made the file dts
/dts-v1/;
