README
README.mdWLED Controller ⚡
A compact ESP32-C3 based controller board for running addressable LED strips with WLED and integrating them into Home Assistant.
What this project includes
- Hardware design files (KiCad project, production outputs, 3D model assets)
- Firmware patch helper for building a patched WLED version
- Assembly references for the current controller revision
⚠️ Current hardware status
Do not order this PCB revision yet — the board still has known issues.
Known issues to fix before ordering
R7/ENpin ofXL1509-5.0Vshould be connected to GND, not input.- ESP32-C3 pin 9 must be pulled correctly for reliable boot.
DS18B20pin must be pulled to 3.3V (fixed on rev 1.6).- More physical spacing is needed for
C1,C3, andC9.

Questions
How big is the Led controller PCB?
It measures 99.9 × 79.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Led controller use?
65 parts, built around the CH330N, ESP32-C3-WROOM-02-H4, DS18B20Z and XL1509-5.0. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Led controller KiCad files?
From the azaslavskis/WLED-Controller repository on GitHub, at the commit this page was made from: the board is hardware/led_controller/led_controller.kicad_pcb and its schematic hardware/led_controller/led_controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Led controller design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
