Questions
How big is the Dot Display PCB?
It measures 96.2 × 96.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dot Display use?
44 parts, built around the LM1117MPX-3.3/NOPB-HXY, SN74LVC1T45DBVRE4 and SK6812. 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 Dot Display KiCad files?
From the humanHardDrive/MatrixPanel repository on GitHub, at the commit this page was made from: the board is Layout/Dot Display/Dot Display.kicad_pcb and its schematic Layout/Dot Display/Dot Display.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dot Display design in my own project?
Its repository states no licence, so its author keeps all rights: ask humanHardDrive before reusing the design.
