Questions

How big is the Unit base PCB?

It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Unit base use?

175 parts, built around the STM32F732RET6, B2B-XH-A and B3B-XH-A. 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 Unit base KiCad files?

From the shinchiryota/Circuit repository on GitHub, at the commit this page was made from: the board is 2024/nhk2024/Unitbase_chachamaru.ver4/unit_base.kicad_pcb and its schematic 2024/MD_Tanukiti/mD.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Unit base design in my own project?

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