Questions
How big is the Skulljack 1 3 PCB?
It measures 40 × 34.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Skulljack 1 3 use?
67 parts, built around the LM321 and BAV70S. 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 Skulljack 1 3 KiCad files?
From the ultimaterobotics/skulljack repository on GitHub, at the commit this page was made from: the board is PCB/skulljack_1_3.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Skulljack 1 3 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).
