Questions
How big is the AVRinator PCB?
It measures 16.5 × 33.6 mm and has 4 copper layers, 1.62 mm thick.
What parts does the AVRinator use?
47 parts, built around the AP2112K-3.3, AP2171WG, TXS0108EPW and USBLC6-2SC6. 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 AVRinator KiCad files?
From the leptun/AVRinator repository on GitHub, at the commit this page was made from: the board is Hardware/AVRinator.kicad_pcb and its schematic Hardware/AVRinator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the AVRinator 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).
