Aside from it going 9-28v, there are no other external model numbers etc, however opening it up revealed a very different configuration inside, using an ESP8285 chip directly on the board.

Identifying this board

Looking closely you can see it’s an ESP8285, on the main board, it has the part number: ZJ-WFMN-B V1.1

Flashing

I found that on the back it has pads to solder to so you can flash it.

board back

The IO0 port is GPIO0 that needs to be pulled to ground when powered on for flashing (as per all ESP devices). I soldered cables to each of these. Note that some are very close to other pads, so be careful. If you want to avoid soldering, also pogo pins work well with the pads.

Configuration

Once flashed run the command to set SetOption15 1 and LedTable 1
