Business Card Information
In development, I have not even started the software. This is open source hardware like all of my designs.
Plastic Frog
Rubber Ducky knockoff. I have sourced USB swivel drive cases. It is surprising how hard that was to find. Trivial to buy with the usb board, and its easy to find just the usb pcb but hard to find the case. Should cost $0.99 to build.

Questions
How big is the CH552Devboard PCB?
It measures 25.6 × 24.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CH552Devboard use?
16 parts, built around the CH552T. 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 CH552Devboard KiCad files?
From the wrickert/CH552 repository on GitHub, at the commit this page was made from: the board is Devboard/CH552Devboard/CH552Devboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the CH552Devboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask wrickert before reusing the design.
