Questions

How big is the The plus PCB?

It measures 262.2 × 76.4 mm and has 2 copper layers, 1.6 mm thick.

What parts does the The plus use?

125 parts, built around the ATMEGA32U4, USBLC6-2SC6 and 1N4148W. 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 The plus KiCad files?

From the Watermelon4man/Plus-version-3 repository on GitHub, at the commit this page was made from: the board is Pcb/the plus.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the The plus design in my own project?

Its repository states no licence, so its author keeps all rights: ask Watermelon4man before reusing the design.
