Questions

How big is the CJ4-Electrical Panel PCB?

It measures 122.4 × 62.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the CJ4-Electrical Panel use?

43 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 CJ4-Electrical Panel KiCad files?

From the neilenns/CJ4-Electrical-Panel repository on GitHub, at the commit this page was made from: the board is CJ4-Electrical-Panel.kicad_pcb and its schematic CJ4-Electrical-Panel.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the CJ4-Electrical Panel design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
