Questions
How big is the Smartdisplay PCB?
It measures 83.2 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Smartdisplay use?
46 parts, built around the ESP32-S3, CH340K, ME6211C33M5G-N and SHT31-DIS-F. 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 Smartdisplay KiCad files?
From the BearLaboratory/smartdisplay-hardware repository on GitHub, at the commit this page was made from: the board is smartdisplay.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Smartdisplay 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).
