Questions
How big is the ELTerm PCB?
It measures 81.6 × 44.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ELTerm use?
31 parts, built around the MAX3232ID, NC7WZ16P6X and SY8120B. 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 ELTerm KiCad files?
From the zephray/ELTerm repository on GitHub, at the commit this page was made from: the board is hardware/ELTerm.kicad_pcb and its schematic hardware/ELTerm.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ELTerm design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
