From the project

Various small synthesizer Voltage Controlled Filter pcbs

- #### These small VCF "plug-in" boards each contain a filter "core". These are intended to be plugged into a motherboard which provides a +/- 12 volt power supply, input/output circuitry, and control voltage sources. - #### They all share an identical mechanical and electrical format. - #### The intended use is to make a bunch of different filters and then be able to easily try them out by swapping the filter plug-in boards into the motherboard.
