README
README.mdWLED-Controller
An all-in-one controller for WS2812B LED strips, made for WLED. With Adapters for LEDs everywhere.
I made this because these WS2812B strips and WLED look so good, but all the other WLED controllers are quite expensive, and I would rather make it by myself. I set out to make it as small as possible, even if that means making it harder for me.
On the controller PCB, I integrated basically a esp32 c3 supermini. That is the bulk of it, but I also put some capacitors on the LED PWR line for smoothing the power out. I also added a P-channel MOSFET to allow for a soft start.
The various adapter PCBs adapt the specified port into 5v and GND and output it to a USB-C, inspired by Framework's modules

Questions
How big is the USB WLED Controller PCB?
It measures 18.3 × 42.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the USB WLED Controller use?
39 parts, built around the ESP32-C3, AMS1117-3.3, SN74LVC4245APWRE4 and ANT3216A063R2400A. 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 USB WLED Controller KiCad files?
From the Choccy-vr/WLED-Controller repository on GitHub, at the commit this page was made from: the board is PCB/USB/USB-WLED-Controller.kicad_pcb and its schematic PCB/Barrel/Barrel_Adapter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the USB WLED Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask Choccy-vr before reusing the design.
