Questions

How big is the Rubberducky PCB?

It measures 36.7 × 18.7 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Rubberducky use?

14 parts, built around the ATMEGA32U4-AU. 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 Rubberducky KiCad files?

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

Can I use the Rubberducky design in my own project?

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