* SoC: MT7620A
* RAM: 64 MB DDR
* Flash: 8MB NOR SPI flash
* WiFi: MT7612E (5Ghz) and builtin MT7620A (2.4GHz)
* LAN: 1x100M
The -factory images can be flashed from the
device's web interface or via nmrpflash.
The device seems to use base PCB as EX3700/EX3800,
but supporting AC1200 using MT7612E.

5.0 GHz 0x8004 *:9a
2.4 GHz 0x4 *:9b

set in flash, it is not used in OpenWrt setup.
