Overview
Serial isolator is an open-source printed circuit board by svanheule, from the svanheule/serial-isolator repository on GitHub. It is a 2-layer board of 17.8 × 12.7 mm with 5 parts on 8 nets, routed with 24 tracks and 0 vias.
Its parts include 2 capacitors, 2 connectors and 1 IC. It belongs with the interfaces and adapters boards of this library.
README
README.mdDual serial isolator
Small board design for a single MAX12930/MAX12931 isolator chip.
Since the MAX12930 and MAX12931 have a similar pin-out, a single board can be used to expose their input and output pins. The spacing of the board's pin rows is chosen such that the board can easily be mounted on a breadboard.
The back side of the board has two areas you can use to indicate in which direction the signals can go, depending on which chip you used to populate the board with.
Note that there is no reverse voltage protection included, so always pay attention when hooking up VCC/GND.

Questions
How big is the Serial isolator PCB?
It measures 17.8 × 12.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Serial isolator use?
5 parts. 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 Serial isolator KiCad files?
From the svanheule/serial-isolator repository on GitHub, at the commit this page was made from: the board is serial-isolator.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Serial isolator design in my own project?
Its repository states no licence, so its author keeps all rights: ask svanheule before reusing the design.
