Questions

How big is the Stesc PCB?

It measures 78.4 × 37.6 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Stesc use?

51 parts, built around the RP2040 and W25Q64JVXGIQ. 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 Stesc KiCad files?

From the murexrobotics/electrical repository on GitHub, at the commit this page was made from: the board is archives/stesc/stesc.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Stesc 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).
