Questions
How big is the Esp32DevKitL PCB?
It measures 71.7 × 72.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp32DevKitL use?
142 parts, built around the K7803-2000R3L and WPM2015-3/TR. 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 Esp32DevKitL KiCad files?
From the Hasatio/esp32DevKitL repository on GitHub, at the commit this page was made from: the board is Rev1/Rev1.kicad_pcb and its schematic Rev0/Rev0.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32DevKitL design in my own project?
Its repository states no licence, so its author keeps all rights: ask Hasatio before reusing the design.
