Questions
How big is the SCELBI TTY Interface PCB?
It measures 114.3 × 85.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SCELBI TTY Interface use?
12 parts, built around the MAX202CPE+ and SN74LS74AN. 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 SCELBI TTY Interface KiCad files?
From the agentorange96/SCELBI repository on GitHub, at the commit this page was made from: the board is SCELBI-TTY-Interface/SCELBI-TTY-Interface.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the SCELBI TTY Interface design in my own project?
Its repository states no licence, so its author keeps all rights: ask agentorange96 before reusing the design.
