Questions

How big is the Max232-adapter PCB?

It measures 59.4 × 34.4 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Max232-adapter use?

10 parts, built around the MAX232N. 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 Max232-adapter KiCad files?

From the okoz/electronics repository on GitHub, at the commit this page was made from: the board is max232-adapter/max232-adapter.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Max232-adapter design in my own project?

Its repository states no licence, so its author keeps all rights: ask okoz before reusing the design.
