Questions
How big is the Esp32 led controller PCB?
It measures 73 × 34 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Esp32 led controller use?
45 parts, built around the ESP32-WROOM-32, AP2172ASG and SN74LV1T08DBV. 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 Esp32 led controller KiCad files?
From the matthewlai/ESP32LEDControl repository on GitHub, at the commit this page was made from: the board is hardware/esp32_led_controller/esp32_led_controller.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32 led controller design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
