Questions
How big is the Shim PCB PCB?
It measures 67.5 × 91.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Shim PCB use?
28 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 Shim PCB KiCad files?
From the WPIRoboticsEngineering/1001-romi-processor-shim repository on GitHub, at the commit this page was made from: the board is shim-PCB/shim-PCB.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Shim PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask WPIRoboticsEngineering before reusing the design.
