Questions
How big is the Dualdrum PCB?
It measures 48 × 109.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dualdrum use?
157 parts, built around the LM13700M, B140HW-7-HXY and CD4001S. 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 Dualdrum KiCad files?
From the dongero/dualdrum repository on GitHub, at the commit this page was made from: the board is p2/dualdrum.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dualdrum design in my own project?
Its repository states no licence, so its author keeps all rights: ask dongero before reusing the design.
