Questions

How big is the BREAD Slice PCB?

It measures 70 × 100 mm and has 2 copper layers, 1.85 mm thick.

What parts does the BREAD Slice use?

38 parts, built around the AP63205WU, 1101M2S3CQE2 and WS2812B-5050RGB. 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 BREAD Slice KiCad files?

From the feastorg/Slice_DCMT repository on GitHub, at the commit this page was made from: the board is hardware/BREAD_Slice.kicad_pcb and its schematic archive/hw_archive/g1-2021-06-08-mtu/BREAD_Slice.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the BREAD Slice 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).
