README
README.mdQeteshs 2-Color LED Bar Controller
This controller replaces the cable bound remote control for a 2-Color USB LED bar and includes an ESP32-WROOM-32 for connecting it to home automation
The board also features a USB-C port for power, a 3-Pin PH2.0 plug for connecting the LED bar and four buttons to control power, brightness and light-temperature.
All parts on the top side are selected from the JLCPCB basic library for cheap production. The ESP module and the connectors need manual soldering on the bottom side unless two-sided pcb assembly is used.

Questions
How big is the LED Bar Controller PCB?
It measures 46 × 44 mm and has 4 copper layers, 1.6 mm thick.
What parts does the LED Bar Controller use?
43 parts, built around the ESP32-WROOM-32, AMS1117-3.3 and AO3400A. 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 Bar Controller KiCad files?
From the Qeteshpony/LED-Bar-Controller repository on GitHub, at the commit this page was made from: the board is pcb/LED-Bar-Controller.kicad_pcb and its schematic pcb/LED-Bar-Controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LED Bar Controller design in my own project?
Its repository publishes it under the BSD-2-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
