Questions
How big is the Basic nano acia PCB?
It measures 17.8 × 36.6 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Basic nano acia use?
16 parts, built around the ATMEGA328P-AU and X322516MLB4SI. 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 Basic nano acia KiCad files?
From the gcoonrod/retro-stack repository on GitHub, at the commit this page was made from: the board is boards/basic-nano-acia/basic-nano-acia.kicad_pcb and its schematic boards/6502-min-sbc/6502-min-sbc.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Basic nano acia design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
