Questions
How big is the Attiny usb panel PCB?
It measures 84.7 × 53.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Attiny usb panel use?
91 parts, built around the ATTINY85-20PU and SK6812. 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 Attiny usb panel KiCad files?
From the arrowtip/attiny-usb_pcb repository on GitHub, at the commit this page was made from: the board is panel/attiny-usb_panel.kicad_pcb and its schematic attiny-usb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Attiny usb panel design in my own project?
Its repository publishes it under the MPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
