Questions

How big is the DX32G PCB?

It measures 53.3 × 45.7 mm and has 2 copper layers, 1.6 mm thick.

What parts does the DX32G use?

34 parts, built around the ESP32-S3-WROOM-1-N8, CH340N, AMS1117-3.3 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 DX32G KiCad files?

From the TheRegularDX/DX32G repository on GitHub, at the commit this page was made from: the board is DX32G.kicad_pcb and its schematic DX32G.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the DX32G design in my own project?

Its repository publishes it under the CERN-OHL-S-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).
