ramips: add support for Edimax EW-7476RPC / EW-7478AC
SoC: MediaTek MT7620a @ 580MHz RAM: 64M (Winbond W9751G6KB-25) FLASH: 8MB (Macronix) WiFi: SoC-integrated: MediaTek MT7620a bgn WiFi: MediaTek MT7612EN nac GbE: 1x (RTL8211E) BTN: WPS - RFKILL/RF 50%/RF 100% toggle LED: - Wifi 5g (blue) - Wifi 2g (blue) - Crossband (green) - Power (green) - WPS (green) - LAN (Green) UART: UART is present as Pads with throughholes on the PCB. They are located next to the switch for the wifi configuration 3.3V - RX - GND - TX / 57600-8N1 3.3V is the square pad Installation ------------ Update the factory image via the web-interfaces (by default: 192.168.9.2/24). http://192.168.9.2/index.asp ramips: add Edimax EW-7478AC SoC: MediaTek MT7620a @ 580MHz RAM: 64M (Winbond W9751G6KB-25) FLASH: 8MB (Macronix) WiFi: SoC-integrated: MediaTek MT7620a bgn WiFi: MediaTek MT7612EN nac GbE: 1x (RTL8211E) BTN: WPS - RFKILL/RF 50%/RF 100% toggle LED: - Wifi 5g (blue) - Wifi 2g (blue) - Crossband (green) - Power (green) - WPS (green) - LAN (Green) UART: UART is present as Pads with throughholes on the PCB.
