Questions
How big is the Esp32lcd PCB?
It measures 78 × 44 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp32lcd use?
30 parts, built around the CH340C, ESP32-WROOM-32D, TPS54302 and MMBT2222A. 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 Esp32lcd KiCad files?
From the cjheath/esp32lcd repository on GitHub, at the commit this page was made from: the board is hardware/esp32lcd.kicad_pcb and its schematic hardware/esp32lcd.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32lcd design in my own project?
Its repository states no licence, so its author keeps all rights: ask cjheath before reusing the design.
