Questions
How big is the Rs232 iso PCB?
It measures 90 × 84.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rs232 iso use?
344 parts, built around the FT231XS-R, MCP1623-I/MC, SN74LVC1T45DBV and TPD2S017DBV. 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 iso KiCad files?
From the greenscreenflicker/rs232iso repository on GitHub, at the commit this page was made from: the board is v2/rs232_iso.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rs232 iso design in my own project?
Its repository states no licence, so its author keeps all rights: ask greenscreenflicker before reusing the design.
