Questions
How big is the Atmega485V PCB?
It measures 48.5 × 81.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Atmega485V use?
34 parts, built around the ATTINY414-SSN, MAX485ED, AMS1117-5.0 and AO3407A. 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 Atmega485V KiCad files?
From the Shaiv123/atmega485V repository on GitHub, at the commit this page was made from: the board is Hardware/atmega485V.kicad_pcb and its schematic Hardware/atmega485V.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Atmega485V 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).
