Questions

How big is the PCBA DEBUG ACCESSORY PCB?

It measures 38 × 25 mm and has 2 copper layers, 0.8 mm thick.

What parts does the PCBA DEBUG ACCESSORY use?

16 parts, built around the TD-1106SN-4.3H-250 and U261-241N-4BS60. 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 ACCESSORY 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-ACCESSORY/PCBA-DEBUG-ACCESSORY.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the PCBA DEBUG ACCESSORY 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).
