- Flash: 256MB NAND
- RAM: 256MB
- Ethernet: Built-in, 2 x 1GbE
- Wifi: MT7603 2.4 GHz, MT7615 5 GHz (4x internal antennas)
- USB: 1x 3.0

Serial:
There is a black block connector next to the red ethernet connector. It
is accessible also through holes in the casing.
Pinout (TTL 3.3V)

Firmware:
The vendor firmware is a fork of OpenWrt (Reboot) with a kernel version
4.4.93. The flash is arranged as below and there is a dual boot
mechanism alternating between rootfs_0 and rootfs_1.
+-------+------+------+-----------+-----------+
| | env1 | env2 | rootfs_0 | rootfs_1 |
| +------+------+-----------+-----------+
| | UBI volumes |
+-------+-------------------------------------+
|U-Boot | UBI |
+-------+-------------------------------------+
|mtd0 | mtd1 |
+-------+-------------------------------------+
| NAND |
+---------------------------------------------+
In OpenWrt rootfs_0 will be used as a boot partition that will contain the
kernel and the dtb. The squashfs rootfs and overlay are standard OpenWrt
behaviour.
+-------+------+------+-----------+--------+------------+
| | env1 | env2 | rootfs_0 | rootfs | rootfs_data|
| +------+------+-----------+--------+------------+
| | UBI volumes |
+-------+-----------------------------------------------+
|U-Boot | UBI |
+-------+-----------------------------------------------+
|mtd0 | mtd1 |
+-------+-----------------------------------------------+
| NAND |
+-------------------------------------------------------+
U-boot:
With proper serial access booting can be halted to U-boot by pressing any
key. TFTP and flash writes are available, but only the first one has been
tested.
NOTE: Recovery mode can be accessed by holding down the reset button while
powering on the device. The led 'Update' will show a solid green light
once ready. A web server will be running at 192.168.1.1:80 and it will
allow flashing a firmware package. You can cycle between rootfs_0 and
rootfs_1 by pressing the reset button once.
Root password:
With the vendor web UI create a backup of your settings and download the
archive to your computer. Within the archive in the file
/etc/shadow replace the password hash for root with that of a password you
know. Restore the configuration with the vendor web UI and you will have
changed the root password.
SSH access:
You might need to enable the SSH service for LAN interface as by default
it's enabled for WAN only.
Installing OpenWrt:
With the vendor web UI install the OpenWrt factory image. Alternatively,
ssh to the device and use sysupgrade -n from cli.
Finalize by installing the OpenWrt sysupgrade image to get a fully
functioning system.
Reverting to the vendor firmware:
Boot with OpenWrt initramfs image
- Remove volumes rootfs_0, rootfs and rootfs_data and create vendor
volumes.
ubirmvol /dev/ubi0 -n 2
ubirmvol /dev/ubi0 -n 3
ubirmvol /dev/ubi0 -n 4
ubimkvol /dev/ubi0 -N rootfs_0 -S 990
ubimkvol /dev/ubi0 -N rootfs_1 -S 990
Power off and enter to the U-boot recovery to install the vendor
firmware.
Known issues:
- MACs for wifi are stored in currently unknown place but it seems
to persist over power-off. They might be stored on the chip.
