Features
This module produces a pulse/square wave at 9Vpp.
There are two knobs. Knob 1 controls the frequency. Knob 2 controls the pulse width.
The module can be powered using a 9V power supply. A battery should work too.

Questions
How big is the SynthCard PCB?
It measures 88.9 × 50.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SynthCard use?
16 parts, built around the NE555P. 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 SynthCard KiCad files?
From the benjiaomodular/SynthCard repository on GitHub, at the commit this page was made from: the board is KiCAD/SynthCard v1.1/SynthCard.kicad_pcb and its schematic KiCAD/SynthCard v1.0/SynthCard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SynthCard design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
