Questions
How big is the BlockBoxController PCB?
It measures 80.5 × 40 mm and has 4 copper layers, 1.61 mm thick.
What parts does the BlockBoxController use?
97 parts, built around the DMG2302UK and NX138BKR. 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 BlockBoxController KiCad files?
From the BlockWorker/ModularAudio repository on GitHub, at the commit this page was made from: the board is BlockBoxController/BlockBoxController.kicad_pcb and its schematic 12VLDO/12VLDO.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BlockBoxController design in my own project?
Its repository states no licence, so its author keeps all rights: ask BlockWorker before reusing the design.
