Questions
How big is the 6AI 4AO PCB?
It measures 85 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 6AI 4AO use?
87 parts, built around the ADM485AQ, BC307 and BC337. 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 6AI 4AO KiCad files?
From the thoczek/Modbus-IO repository on GitHub, at the commit this page was made from: the board is 6AI_4AO/Board/6AI_4AO.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the 6AI 4AO design in my own project?
Its repository publishes it under the LGPL-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).
