Questions

How big is the DockingStation PCB?

It measures 147.2 × 63.2 mm and has 4 copper layers, 1.6 mm thick.

What parts does the DockingStation use?

218 parts, built around the 74VHCT244D and DS14C535MSA. 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 DockingStation KiCad files?

From the ahmadexp/Open-Source-PC110 repository on GitHub, at the commit this page was made from: the board is Mods/NewDock/DockingStation.kicad_pcb and its schematic Mods/CPU Upgrade/bgacpu-dualcon/bgacpu-dualcon.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the DockingStation design in my own project?

Its repository states no licence, so its author keeps all rights: ask ahmadexp before reusing the design.
