Questions
How big is the USB RS232 Converter PCB?
It measures 33 × 41.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the USB RS232 Converter use?
29 parts, built around the MAX3232ID, FT230XQ-R, TPD1E05U06DPYR and TPD1E10B06DPYR. 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 USB RS232 Converter KiCad files?
From the mirjunaid/USB-RS232_Converter repository on GitHub, at the commit this page was made from: the board is USB-RS232_Converter/USB-RS232_Converter.kicad_pcb and its schematic USB-RS232_Converter/USB-RS232_Converter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the USB RS232 Converter design in my own project?
Its repository states no licence, so its author keeps all rights: ask mirjunaid before reusing the design.
