Questions
How big is the WiringHarness PCB?
It measures 64 × 40 mm and has 4 copper layers, 1.6 mm thick.
What parts does the WiringHarness use?
37 parts, built around the LDL212PU50R, LDL212PV33R, PCA9306DCTR and TC33X-2-102E. 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 WiringHarness KiCad files?
From the TadAtThayer/MazeController repository on GitHub, at the commit this page was made from: the board is ConnectorBoard/WiringHarness/WiringHarness.kicad_pcb and its schematic ConnectorBoard/WiringHarness/WiringHarness.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the WiringHarness design in my own project?
Its repository states no licence, so its author keeps all rights: ask TadAtThayer before reusing the design.
