Questions
How big is the Arduino Shield Intro PCB?
It measures 68.6 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Arduino Shield Intro use?
34 parts, built around the LM358. 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 Arduino Shield Intro KiCad files?
From the Hemo-Dyn/EXG-Bridge repository on GitHub, at the commit this page was made from: the board is Phases/Phase-1/Arduino_Shield_Intro.kicad_pcb and its schematic Phases/Phase-0/Basic-PCB/Basic-PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Arduino Shield Intro 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).
