Unbranded Smart Plug BSD01

esp8266 global us Comes with ESPHome plug

Overview

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.

GPIO Pinout

Pin	Function
GPIO1	Status LED - Red
GPIO12	Relay
GPIO13	Button (inverted)
GPIO14	Status LED - Blue (inverted)
