Questions

How big is the General Nano PCB?

It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.

What parts does the General Nano use?

57 parts, built around the IRF540N. 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 General Nano KiCad files?

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

Can I use the General Nano design in my own project?

Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
