Questions
How big is the Unit PCB?
It measures 35 × 161.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Unit use?
26 parts, built around the MCP3008-I/P, 74HC165D and 74HC595. 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 KiCad files?
From the YaelCAV/2425_Maker_MuseMatrix repository on GitHub, at the commit this page was made from: the board is Hardware/PCB_CAD/Unit/Unit.kicad_pcb and its schematic Hardware/PCB_CAD/MuseMatrix_Core/Column_7_Rows.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Unit design in my own project?
Its repository states no licence, so its author keeps all rights: ask YaelCAV before reusing the design.
