Overview
2164SVF is an open-source printed circuit board by JordanAceto, from the JordanAceto/SSM2164-SVF repository on GitHub, published under the CC-BY-4.0 licence. It is a 2-layer board of 58.4 × 99.1 mm with 77 parts on 48 nets, routed with 389 tracks and 60 vias.
It is built around the TL072, PJ301M-12 and 1N4148W, with the BAT48 among its other parts. Its parts include 25 capacitors, 25 resistors, 8 connectors, 6 diodes and 5 ICs. It belongs with the audio and music boards of this library.

SCHEMATIC
Eurorack friendly pcb with mouting holes if flying wire construction is desired.
Range switch allows for super low frequency mode, which can be used as a sine wave LFO, or for creating "bouncy ADSRs", etc.
When used as a sine LFO, note that the band-pass and low-pass outputs are 90 ° out of phase with each other, and the high-pass and low-pass outputs are 180 ° out of phase. With a couple of inverters you can have 0 °, 90 °, 180 °, and 270 ° outputs.
Note that the amplitude of the self oscillation is not perfectly flat across the frequency range, and may even peter out at very low frequencies. Additionally the sine wave appearing at the band-pass output is a little lower in amplitude than the other two. Don't expect amazing performance as a quadrature LFO, but I still find this to be a useful feature in a small system.

What parts does the 2164SVF use?
77 parts, built around the TL072, PJ301M-12, 1N4148W and BAT48. 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 2164SVF KiCad files?
From the JordanAceto/SSM2164-SVF repository on GitHub, at the commit this page was made from: the board is main_pcb/kicad_docs/2164SVF.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the 2164SVF design in my own project?
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
