Questions

How big is the Buzzcar main PCB?

It measures 149.9 × 81.3 mm and has 2 copper layers, 1.69 mm thick.

What parts does the Buzzcar main use?

36 parts, built around the ESP32-C6-DEVKITC-1-N8, ROB-14450 and LM324N. 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 Buzzcar main KiCad files?

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

Can I use the Buzzcar main 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).
