Questions
How big is the TimeMachineCpu PCB?
It measures 86 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TimeMachineCpu use?
25 parts, built around the ESP32-DEVKITC-VE and BC817. 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 TimeMachineCpu KiCad files?
From the zverinec/spacetime-stapler repository on GitHub, at the commit this page was made from: the board is cpu/hw/TimeMachineCpu.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the TimeMachineCpu 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).
