Questions
How big is the WLED ESP32 Controller PCB?
It measures 62.2 × 30.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the WLED ESP32 Controller use?
24 parts, built around the ESP32-WROOM-32, SN74AHCT125D and AMS1117-3.3. 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 WLED ESP32 Controller KiCad files?
From the Hasenpups/WLED_ESP32_Controller repository on GitHub, at the commit this page was made from: the board is KiCad/WLED_ESP32_Controller.kicad_pcb and its schematic KiCad/WLED_ESP32_Controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the WLED ESP32 Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask Hasenpups before reusing the design.
