Yet Another WLED Controller

This repository contains a schematic and PCB layout for a yet another WLED controller (yawl-controller).

This is the ESP8266 based wireless pixel controller to drive addressable LED strips like WS2812B/APA102/WS2801/etc using WLED.

Features

Compact: 60x35x19mm with case, 59x32x12mm without case.
Supports 3-wire and 4-wire LED strips.
Fuse for overcurrent protection.
Reverse polarity protection.
Modern SN74LVC2T45 bus transceiver with voltage translation. Why?
Capacitor 1000 µF at 6.3V, smooths the voltage and sudden changes in demand for current from the LEDs.
IR receiver (optional).
Button (optional).
Dallas temperature sensor for measuring ambient temperature inside of enclosure (optional).
Connection to relay for reducing power consumption when seemingly switched off (optional).

Some credits

Thanks to Christian Schwinne aka Aircoookie who created an excelent WLED Project - a fast and feature-rich implementation of an ESP8266/ESP32 webserver to control NeoPixel (WS2812B, WS2811, SK6812) LEDs or also SPI based chipsets like the WS2801 and APA102.

Schematics are based on manufacturers datasheets but some component values come from Adafruit Learning System so thanks to Adafruit for keeping their products open source.
