Questions

How big is the Tmc dev board PCB?

It measures 30.5 × 22.2 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Tmc dev board use?

11 parts. 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 Tmc dev board KiCad files?

From the ChipCE/juice-plus-pcb repository on GitHub, at the commit this page was made from: the board is tmc-dev-board/tmc-dev-board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Tmc dev board 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).
