Questions
How big is the ESP32-S3-MegaMultiFunction PCB?
It measures 165.1 × 132.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32-S3-MegaMultiFunction use?
245 parts, built around the ESP32-S3FN8, TC4428COA, TC4426EOA and PCA9685PW. 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-S3-MegaMultiFunction KiCad files?
From the RobertPHeller/ESP32-LCC repository on GitHub, at the commit this page was made from: the board is ESP32-S3-MegaMultiFunction/ESP32-S3-MegaMultiFunction.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32-S3-MegaMultiFunction design in my own project?
Its repository states no licence, so its author keeps all rights: ask RobertPHeller before reusing the design.
