Questions

How big is the RACK ESP32S3 PCB?

It measures 482.6 × 44.6 mm and has 2 copper layers, 1.6 mm thick.

What parts does the RACK ESP32S3 use?

188 parts, built around the ME6211C33M5G-N and WS2812B. 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 RACK ESP32S3 KiCad files?

From the ccadic/ESP32S3RACKPCB repository on GitHub, at the commit this page was made from: the board is RACK-ESP32S3.kicad_pcb and its schematic RACK-ESP32S3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the RACK ESP32S3 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).
