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
- Stacks with SYNTH-MIDI-CTL-01 card
