Questions
How big is the Gatekeeper PCB PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Gatekeeper PCB use?
61 parts, built around the ATMEGA328P-AU, IRM-10-12, 2N2222A and S1G. 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 Gatekeeper PCB KiCad files?
From the Ingimarsson/gatekeeper repository on GitHub, at the commit this page was made from: the board is hardware/GK-400-v1/pcb/Gatekeeper PCB.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Gatekeeper PCB 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).
