Questions
How big is the Mcu and pi board PCB?
It measures 143.6 × 215.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Mcu and pi board use?
118 parts, built around the STM32F091CCT6, TPS40305DRCR, CSD17578Q3A and TB006-508-03BE. 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 Mcu and pi board KiCad files?
From the purduerov/X18-ROV-Test-Bench repository on GitHub, at the commit this page was made from: the board is MCU and Pi Board/mcu and pi board/mcu and pi board.kicad_pcb and its schematic MCU and Pi Board/mcu and pi board/mcu and pi board-2025-11-19_162239/mcu and pi board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mcu and pi board design in my own project?
Its repository states no licence, so its author keeps all rights: ask purduerov before reusing the design.
