SYNTH-VCO-01

SYNTH-VCO-01 REV1 FRONT 3D.png

  • Build of Pico VCO by HAGIWO
  • Digital Voltage Controlled Oscillator (VCO)
  • Three modes: Wavefold, FM and AM
  • PWM output with 2 pole low pass filter
  • Each mode has eight built-in waveforms
  • XIAO RP2040 CPU
  • (5) Pushbuttons
    • Octave Up/Down
    • Mode Up/Down (Wavefold, FM and AM)
    • Push Timbre switches between 8 waveforms
  • (2) Knobs
    • Freq fine adjust
    • Mod adjust
  • Standard EuroRack 16 pin header
    • Supports 12V in with on-board 5V regulator
    • 5V regulator can be not installed if 5V is available on EuroRack connection
  • Card is not a Eurorack card
    • Probably too deep, needs cabling
  • (4) 6-32 mounting holes
