Specifications: - SOC: MT7621AT (880 MHz) - DRAM: DDR3 448 MiB (Nanya NT5CC256M16DP-DI) - Flash: 2 MiB SPI NOR (S25FL016K) + 128 MB SPI NAND (W25N02KVZEIR) - Ethernet: 1x 10/100/1000 Mbps (SOC's built-in switch, with PoE+) - Wi-Fi: 2x2:2 2.4/5 GHz (MT7905DAN + MT7975DN) (MT7905DAN doesn't support background DFS scan/BT) - LED: tri-color LED for status (red, blue, green) - Buttons: 1x (reset) - Antenna: 4x internal, non-detachable omnidirectional - UART: 1x 4-pin (2.54 mm pitch, marked as "3V3 G/RX GND W/TX") - Power: 12 V DC/2 A (DC jack) Flashing instructions: ====================== Various methods can be used to install the actual image on the flash. Two easy ones are: ap51-flash ---------- The tool ap51-flash (https://github.com/ap51-flash/ap51-flash) should be used to transfer the image to the u-boot when the device boots up.
