Unbranded Smart Plug BSD01

This device did not have a serial number, brand name or FCC ID. Bought from AliExpress. The plugs I received did not respond to tuya-convert so a hard flash was necessary.

The plug uses a wifi module with ID ajw-02_8285. Not much online but enough to figure out the pin pads for a hard flash. A couple of users have gone before me and desoldered the module from the main board but I chose to solder DuPont cables to the pin pads and then use a pik tool to trigger flash mode via GPIO0. If I can figure out how to upload images here I’ll do that later.

The GPIO pinout was learned from Blakadder Tasmota documentation and adapted through trial and error.
