Questions
How big is the PRO MCU PCB?
It measures 80 × 41 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PRO MCU use?
23 parts, built around the TN0702N3-G. 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 PRO MCU KiCad files?
From the Henning-Klatt/projekt-microcontroller repository on GitHub, at the commit this page was made from: the board is mc_project_4_pcb_layout/PRO_MCU/PRO_MCU.kicad_pcb and its schematic mc_project_4_pcb_layout/PRO_MCU/PRO_MCU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PRO MCU design in my own project?
Its repository states no licence, so its author keeps all rights: ask Henning-Klatt before reusing the design.
