CEfx Solderless Breadboard VCO Synthesizer Module Voltage Controlled Oscillator

Description

A Voltage Controlled Oscillator (VCO) is one of the basic building blocks of a synthesizer. A VCO produces alternating outputs in several waveforms with the frequency (tone) controlled by an input voltage. The higher the input voltage, the higher the output frequency. The input voltage might come from a manual source like a knob, from an instrument like a keyboard, from another synth module, or some esoteric control surface.
This CE
fx
VCO module is based on the Coolaudio V3340M Voltage-Controlled Oscillator.  It features standard 1V-per-octave  tuning, and has three simultaneous outputs: triangle, ramp, and pulse, with a manual- or voltage-controlled pulse width.  Outputs all range from 0V to +4V.  We expect to offer a companion triangle-to-sine converter module soon.  Note that outputs are not buffered. Output impedance is 10K for triangle out, 5K for ramp out, and 3.6K for pulse out.
Features
Based on the Coolaudio V3340 VCO chip
Triangle, ramp, and pluse outputs
Two summed CV inputs plus on-board frequency offset pot
Socketed frequency range capacitor can be swapped out to create a LFO
FM input
About CE

Modules
The Cabintech Experimenters Effects (CE
fx
) modules are specifically built with the experimenter, educator, self-learner, and hobbyist in mind. Each module is designed to work in a solderless breadboard environment giving you the ultimate flexibility to add your own circuits, tear  down and rebuild something new at any time.
These modules supply the basic building blocks of modular synthesizers and/or effects systems. By using the breadboard as a platform you can mix in your own circuits, modify them, and experiment with virtually any idea. Mix and match as your interest takes you, build, rebuild, and change it around at any time.
We also provide a path to a more permanent implementation as a eurorack module or guitar effects pedal if you want to turn your experiment into a permanent addition to your music system. It is all about flexibility and an experimental circuits platform centered around basic synth functions and audio effects blocks.
