Questions

How big is the 2022NHK Source PCB?

It measures 73.7 × 75.4 mm and has 2 copper layers, 1.6 mm thick.

What parts does the 2022NHK Source use?

22 parts, built around the L7805. 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 2022NHK Source KiCad files?

From the nalinally/robocon repository on GitHub, at the commit this page was made from: the board is 2022NHK/circuits/robot/2022NHK_Source/2022NHK_Source.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the 2022NHK Source design in my own project?

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