Questions

How big is the PCBA DEBUG UART PCB?

It measures 38 × 25 mm and has 4 copper layers, 1 mm thick.

What parts does the PCBA DEBUG UART use?

28 parts, built around the CH340X, CH334R, LN1134A332MR-G and TD-1106SN-4.3H-250. 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 PCBA DEBUG UART KiCad files?

From the intechstudio/grid-hardware repository on GitHub, at the commit this page was made from: the board is Electrical/Design/PCBA-DEBUG-UART/PCBA-DEBUG-UART.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the PCBA DEBUG UART 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).
