Questions
How big is the Quadulator PCB?
It measures 144.1 × 181.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Quadulator use?
128 parts, built around the MCP6004-E/P, 74HC595, CD4051BE and L7805. 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 Quadulator KiCad files?
From the GlobalSequence/quadulator repository on GitHub, at the commit this page was made from: the board is hardware/quadulator.kicad_pcb and its schematic hardware/control_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Quadulator design in my own project?
Its repository states no licence, so its author keeps all rights: ask GlobalSequence before reusing the design.
