Power: 12V 2.5A

Flash instruction:
1. Serve the initramfs.img using a TFTP server with address 10.10.10.3.
2. Interrupt the uboot startup process via UART.
3. Select "System Load Linux to SDRAM via TFTP" item.
4. (important) Back up firmware(mtd7) partitions with:
    dd if=/dev/mtd7 of=/tmp/firmware.bin
    and then download the firmware.bin image via SCP.
5. Flash the OpenWrt sysupgrade firmware.

Recovery stock firmware:

1. Transfer the firmware.bin image to the device.
