Questions
How big is the Rasp usb PCB?
It measures 20 × 32.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rasp usb use?
23 parts, built around the CP2104EK and AMS1117-5.0. 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 Rasp usb KiCad files?
From the jfcamel/usb_rasp_mini repository on GitHub, at the commit this page was made from: the board is rasp_usb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rasp usb design in my own project?
Its repository states no licence, so its author keeps all rights: ask jfcamel before reusing the design.
