ramips: add Edimax EW-7478APC
SoC: MediaTek MT7620a @ 580MHz
RAM: 64M (Winbond W9751G6KB-25)
FLASH: 8MB (Macronix)
WiFi: SoC-integrated: MediaTek MT7620a bgn
WiFi: MediaTek MT7612EN nac
Switch: Mediatek MT7530W Gigabit Switch (4 x LAN, 1 x WAN)
USB: Yes 1 x 2.0 (+ 1 x 2.0 unpopulated header)
BTN: Reset/WPS
LED: - Power (white)
- Internet (blue)
- Wifi (blue)
- USB (blue)
UART: UART is present as pads with throughholes on the PCB. They are
located in the lower right corner (GbE ports facing up)
3.3V - RX - GND - TX / 57600-8N1
3.3V is the square pad
Installation
------------
Update the factory image via the web-interfaces (by default:
http://edimax.setup)
