From the project

Various small synthesizer Voltage Controlled Filter pcbs

Small MS20 based low pass/high pass filter PCB, designed to plug into a larger motherboard.

MS20 based LPF/HPF with voltage controlled feedback. This PCB includes the audio path and CV inputs for frequency and feedback, but does not include any modulation sources.

The intended use for this board is to plug in to a larger motherboard which contains slots for one or more of these plug-in boards, as well as modulation sources, panel controls, and input/output routing.
