Simple ESP8266-based and WLED-powered LED controller board
SimpleWLED8266 is a simple, ESP8266-based, and WLED-powered LED controller board, supporting both analog and digital LED strips. The board features AO3400 mosfets to drive the analog LEDs and uses the 74AHCT125 buffer as a level-shifter for the digital LEDs which require 5V.
The board is very simple to solder since it only features a few parts and the smallest SMD part is of the size 0805. It does not use a switching regulator, reducing complexity and noise, but also decreasing the efficiency of the board. Make sure to pick 1117 regulators that support input voltages >12V! (e.g., LM1117 by…
