Questions
How big is the Quick nic PCB?
It measures 50 × 20 mm and has 6 copper layers, 1.6 mm thick.
What parts does the Quick nic use?
26 parts, built around the RTL8153B-VB-CG, CH217A, HC-USB3.0-C26 and HR911130A. 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 Quick nic KiCad files?
From the tobycm/quick-nic repository on GitHub, at the commit this page was made from: the board is pcb/quick-nic.kicad_pcb and its schematic pcb/quick-nic.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Quick nic 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).
