Questions
How big is the 6U5 MCU Board PCB?
It measures 20 × 52 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 6U5 MCU Board use?
28 parts, built around the MCP6001T-I/OT(MS) and BC847C. 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 6U5 MCU Board KiCad files?
From the donpivo/TuningIndicator_6U5 repository on GitHub, at the commit this page was made from: the board is Schematic/6U5_MCU_Board/6U5_MCU_Board.kicad_pcb and its schematic Schematic/6U5_MCU_Board/6U5_MCU_Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 6U5 MCU Board design in my own project?
Its repository states no licence, so its author keeps all rights: ask donpivo before reusing the design.
