Questions

How big is the TestCard PCB?

It measures 101.3 × 76.7 mm and has 4 copper layers, 1.6 mm thick.

What parts does the TestCard use?

18 parts, built around the 74ALVC164245DL. 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 TestCard KiCad files?

From the MicroLind-Developers/microlind-hw repository on GitHub, at the commit this page was made from: the board is peripherals/WIP/TestCard/TestCard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the TestCard design in my own project?

Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
