• WLED running on an esp8266 -- specifically the Wemos D1 Mini
  
• To get 5v for the esp8266 I'm using an eBoot Mini Buck Converter ** Note that these buck converters can be very sensitive, I managed to short one with a screwdriver while trying to get the proper voltage tuned.
• The power supply that came with the govee is 12v DC, that power can go directly through to the led strip on the red and black lines (red is power, black is ground). The white line is the data line which we connect to pin D4 on the esp8266. The esp8266 gets power from the buck converter. I've included a wiring diagram below as well as some shots of my test setup (note my test setup used a different buck converter).
