Quadrants is a skiff-friendly SMD version of the Prok Drum Modules.
I love the Prok modules, but the 3-boards sandwich made them too deep to fit in my drum skiff. With this version, the depth is no longer about 40mm, but rather 30mm.

Questions
How big is the Quadrants PCB?
It measures 107.5 × 19.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Quadrants use?
45 parts, built around the MCP6002-I/P, TL072, REG1117 and BAT54S. 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 Quadrants KiCad files?
From the nebularnoise/quadrants repository on GitHub, at the commit this page was made from: the board is quadrants/quadrants.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Quadrants design in my own project?
Its repository states no licence, so its author keeps all rights: ask nebularnoise before reusing the design.
