Questions

How big is the PC ExtensionBoard PCB?

It measures 128.3 × 98.3 mm and has 6 copper layers, 1.6 mm thick.

What parts does the PC ExtensionBoard use?

269 parts, built around the STM32G0B1RCT6, CH224K, TPS56C230RJER and ESD204DQAR. 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 PC ExtensionBoard KiCad files?

From the caotiendattx/PC_ExtensionBoard repository on GitHub, at the commit this page was made from: the board is PC_ExtensionBoard/PC_ExtensionBoard.kicad_pcb and its schematic PC_ExtensionBoard/HDMI.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the PC ExtensionBoard design in my own project?

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