Questions

How big is the Neo PCB?

It measures 119.1 × 121 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Neo use?

137 parts, built around the ESP32-S3-WROOM-1-N8, IR2111, 112J-TDAR-R01 and L7812. 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 Neo KiCad files?

From the IstratieStefan/Neo repository on GitHub, at the commit this page was made from: the board is Neo.kicad_pcb and its schematic ESP32.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Neo 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).
