This is an voltage controlled oscillator (VCO) with great precision, designed to be stable even in the case of power supply fluctuations. It’s able to track with a precission of 1 Cent from C0 to C7, 4 Cents in C8 and 13 Cents in C9.

This is the latest revision with the temperature compensation upgrade for improved tracking over a wider octave range.

This kit includes all the board components presoldered, only the mechanical parts needs to be assembled.
