Questions
How big is the ARIII PCB?
It measures 114 × 96 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ARIII use?
34 parts, built around the 74LS74PC, MC1455BD, ZVP2106A and 3386F-1-103LF. 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 ARIII KiCad files?
From the na103/ar3 repository on GitHub, at the commit this page was made from: the board is Kicad/ARIII/ARIII.kicad_pcb and its schematic Kicad/ARIII/ARIII.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ARIII design in my own project?
Its repository states no licence, so its author keeps all rights: ask na103 before reusing the design.
