Questions

How big is the Smurf box PCB?

It measures 120 × 70 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Smurf box use?

41 parts, built around the ESP32-DEVKITC-VE, SN74HC08N and PN2222A. 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 Smurf box KiCad files?

From the semteXKG/fiesta-hardware repository on GitHub, at the commit this page was made from: the board is cad/smurf-box/smurf-box.kicad_pcb and its schematic cad/smurf-box/smurf-box.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Smurf box design in my own project?

Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
