Questions

How big is the TES Aurora PCB?

It measures 77.2 × 91.4 mm and has 2 copper layers, 1.6 mm thick.

What parts does the TES Aurora use?

34 parts, built around the 74HCT125PW. 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 TES Aurora KiCad files?

From the tomcombriat/TES_Aurora repository on GitHub, at the commit this page was made from: the board is hardware/v1/v1.kicad_pcb and its schematic hardware/v1/v1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the TES Aurora 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).
