Questions
How big is the Prezenter PCB?
It measures 38.1 × 69.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Prezenter use?
13 parts, built around the ESP32-WROOM-32. 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 Prezenter KiCad files?
From the onismond/Prezenter repository on GitHub, at the commit this page was made from: the board is Prezenter/Prezenter.kicad_pcb and its schematic Prezenter/Prezenter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Prezenter design in my own project?
Its repository states no licence, so its author keeps all rights: ask onismond before reusing the design.
