VCO: common questions

How big is the VCO PCB?

The VCO measures 50 × 200 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the VCO?

87 components, from 42 distinct parts. The full bill of materials is listed on this page.

Where can I download the VCO design files?

From the telec16/modular-synth repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the VCO design in my own project?

The repository has no license, so all rights stay with telec16. Use it as a reference, and ask the author before reusing the design.
