Questions
How big is the Prrojectop PCB?
It measures 29.7 × 126.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Prrojectop use?
45 parts, built around the CP2102, ESP-12E, SS8050 and SI2301. 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 Prrojectop KiCad files?
From the Editbyfox/PCB-Project repository on GitHub, at the commit this page was made from: the board is Prrojectop.kicad_pcb and its schematic Prrojectop.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Prrojectop design in my own project?
Its repository states no licence, so its author keeps all rights: ask Editbyfox before reusing the design.
