Questions
How big is the Usb auto reboot PCB?
It measures 14.2 × 26 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Usb auto reboot use?
11 parts, built around the CH32V003J4M6 and CH217K. 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 Usb auto reboot KiCad files?
From the 74th/usb-rebooter repository on GitHub, at the commit this page was made from: the board is pcb/usb_auto_reboot.kicad_pcb and its schematic pcb/usb_auto_reboot.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usb auto reboot design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
