Questions
How big is the Main 4layer PCB?
It measures 80 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Main 4layer use?
37 parts, built around the TEENSY 4.1 and J00-0045NL. 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 Main 4layer KiCad files?
From the RoboJackets/urc-electrical repository on GitHub, at the commit this page was made from: the board is boards/Main_4layer/Main_4layer/Main_4layer.kicad_pcb and its schematic boards/Main/Main/Main.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Main 4layer design in my own project?
Its repository states no licence, so its author keeps all rights: ask RoboJackets before reusing the design.
