Questions

How big is the GW4194-SOJ DC PCB?

It measures 88.9 × 20.3 mm and has 4 copper layers, 1.6 mm thick.

What parts does the GW4194-SOJ DC use?

21 parts, built around the 74LVC1G04Z, 74LVC1G32Z and 74LVC1G74DC. 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 GW4194-SOJ DC KiCad files?

From the garrettsworkshop/RAMSIMM-30 repository on GitHub, at the commit this page was made from: the board is GW4194-4MB-CBRFIX-SOJ-DC/GW4194-SOJ-DC.kicad_pcb and its schematic GW4190-4MB-SOJ/GW4190-SOJ.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the GW4194-SOJ DC design in my own project?

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