Questions

How big is the LedCAN PCB?

It measures 59.7 × 15.2 mm and has 4 copper layers, 1.6 mm thick.

What parts does the LedCAN use?

43 parts, built around the M0A23EC1AC, MPQ4569GQ-AEC1-Z, UCC27282DRCR and PSMQC076N12LS1. 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 LedCAN KiCad files?

From the MIH-pi/ledCAN repository on GitHub, at the commit this page was made from: the board is kicad/ledCAN/ledCAN.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the LedCAN design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
