Questions
How big is the Isolated Serial PCB PCB?
It measures 55.9 × 38.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Isolated Serial PCB use?
26 parts, built around the IL0505S and ADUM1201AR. 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 Isolated Serial PCB KiCad files?
From the juarendra/Isolated-Serial-PCB repository on GitHub, at the commit this page was made from: the board is PCB/KICAD/Isolated-Serial-PCB.kicad_pcb and its schematic PCB/KICAD/Isolated-Serial-PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Isolated Serial PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask juarendra before reusing the design.
