Questions
How big is the RS232 PCB?
It measures 125 × 113 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RS232 use?
27 parts, built around the MAX232N and BC548. 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 RS232 KiCad files?
From the ibm2030/EDUC8 repository on GitHub, at the commit this page was made from: the board is E8Serial/RS232/RS232.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the RS232 design in my own project?
Its repository states no licence, so its author keeps all rights: ask ibm2030 before reusing the design.
