Questions
How big is the OscillatorBoard PCB?
It measures 54.6 × 44.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the OscillatorBoard use?
11 parts, built around the STP16CP05T, 74AHC1G02GW, 74AHC1G04SE and MAX7375AXR105. 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 OscillatorBoard KiCad files?
From the KubbyDev/MusicBox repository on GitHub, at the commit this page was made from: the board is Modules/StepperMotors/OscillatorBoard/OscillatorBoard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the OscillatorBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask KubbyDev before reusing the design.
