Questions
How big is the Usbpcb PCB?
It measures 41.4 × 54.6 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Usbpcb use?
19 parts, built around the ESP-12F and B3U-1000P. 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 Usbpcb KiCad files?
From the marmbrus/circuits repository on GitHub, at the commit this page was made from: the board is usbpcb/usbpcb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usbpcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask marmbrus before reusing the design.
