Questions

How big is the ExOneMicrorocessor PCB?

It measures 33.5 × 62.7 mm and has 2 copper layers, 1.6 mm thick.

What parts does the ExOneMicrorocessor use?

40 parts, built around the STM32G041C8T6, FT230XS-R and UJ2-MBH-3-SMT-TR. 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 ExOneMicrorocessor KiCad files?

From the j-exinia/Custom-Microcontroller repository on GitHub, at the commit this page was made from: the board is ExOneMicrorocessor/ExOneMicrorocessor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the ExOneMicrorocessor design in my own project?

Its repository states no licence, so its author keeps all rights: ask j-exinia before reusing the design.
