README
hardware/debug_bridge_r2/README.mdPixel C debug bridge, rev2
Debugging device for use with Pixel C. Supports the following configurations:
-
Pixel C as host: Configures the Pixel C to act as a USB host, then breaks out two host ports via a hub. Useful for demos, for connecting keyboard and mouse, etc.
-
Pixel C as debug device: Configures the Pixel C in debug mode, and joins the main device port and the debug port via a second hub to a single convenient micro-B debug connector.
Revision 2 is a complete reimplementation, and is still untested at this point.

Questions
How big is the Ais usbc PCB?
It measures 49.2 × 28 mm and has 4 copper layers, 0.8 mm thick.
What parts does the Ais usbc use?
61 parts, built around the ATTINY48-MMU, USB2512B/M2, 74HC1G04GW and TLV70233DBV. 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 Ais usbc KiCad files?
From the xenbedded/pixel-c-support repository on GitHub, at the commit this page was made from: the board is hardware/debug_bridge_r2/ais-usbc.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ais usbc design in my own project?
Its repository states no licence, so its author keeps all rights: ask xenbedded before reusing the design.
