Xiaomi Mi WiFi Range Extender AC1200 Model RA75

This is compact, wall-wart type range extender with 2×2 Wifi5 Dual band hardware. 20€ in 2022 in Germany, taxes included. Installation is done through an app, there is no HTML UI. If you don't mind some soldering, this is a very capable hardware for the price that runs openwrt just fine. Major hardware limitation (if you don't count the form factors inherent lack of interfaces) is the 100M LAN port and the 64M of RAM.

RA75

This is almost the same hardware as mi_router_4a_mir4a_100m and it will run the firmware for this router. Note: Make sure to use the firmware of the chinese version linked above, not the 'international' version, which also exists.

Somewhat cleaner support is upcoming.

This box does not run a HTML UI, it is configured through an app. For this reason, you cannot use OpenWrtInvasion. You have to install it by opening the box, soldering an UART connector, connect an UART 3V Interface, flash via shell and TFTP.

Please note that right now, there is no way back to the stock firmware. (For lack of trying, and why would anybody?)

Use the firmware from mi_router_4a_mir4a_100m

Only known way to install *right now* is open the box, solder in a UART header, connect to console. From there, its rather easy:

After Boot, U-Boot will prompt for: Please choose the operation:

 1: Load system code to SDRAM via TFTP. 
 2: Load system code then write to Flash via TFTP. 
 3: Boot system code via Flash (default).
 4: Entr boot command line interface.
 9: Load Boot Loader code then write to Flash via TFTP. 

With 2 (and having an tftp server running), you can flash the new firmware. Please note that the original firmware has not been yet extracted, so there is no way back!

As long as you haven't shot your bootloader, the serial console install should work

After flashing, proceed with Basic configuration: Set up your Internet connection, configure wireless, configure USB port, etc.

There is a single screw under the barcode label, right side. Removing the screw beneath, you can split the unit into the power supply and the wifi part.

port.serial general information about the serial port, serial port cable, etc.

There is a place for a standard uart header, pinout is written down on the PCB. Can easily be soldered.
