4HP Eurorack Module
Features
- White and pink(ish) noise output
- Sample-and-hold with variable slew rate
- S&H can be triggered by an internal clock or external input
- Internal clock is output on the trigger jack when selected
Notes
This module is built using the Delptronics Module Construction Set which includes PCBs for the front panel controls and other components. The PCB layout file is just a guide showing how I placed the components on the Delptronics boards. (It's a bit of a mess - sorry!)
Please note that I am a hobbyist, not a trained electronics engineer. No guarantees!

Questions
How big is the VCF SV PCB?
It measures 111.5 × 106.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the VCF SV use?
78 parts, built around the TL072. 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 VCF SV KiCad files?
From the Len42/Synth repository on GitHub, at the commit this page was made from: the board is modules/VCF-SV/VCF-SV.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the VCF SV design in my own project?
Its repository states no licence, so its author keeps all rights: ask Len42 before reusing the design.
