Questions
How big is the Usb2most PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Usb2most use?
139 parts, built around the TJA1051T/3/1, ESP32-WROOM-32D, TJA1021T/10/C and LMR14206XMK. 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 Usb2most KiCad files?
From the smartgauges/usb2most repository on GitHub, at the commit this page was made from: the board is hardware-v1/usb2most.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usb2most design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
