Board C
About the Board C
Board C is an open source PCB design by szegedylorant, published on GitHub. It is a 2-layer board measuring 38.1 × 100 mm, with 27 components from 14 distinct parts.
By type, the board carries 10 resistors, 8 connectors, 3 switches, 1 diode and 1 capacitor.
From the project
Arduino(-pico) code for wavetable VCO on Seeed XIAO RP2040 board
Wavetable VCO in 8hp Eurorack format based on the Seeed XIAO RP2040 board
* Chose from 8 wavetable types via push button
* Move around wavetable via potentiometer
Set root note / transpose via potentiometer Fine tuning via same knob while pressing tune button
* Octave switch for -1 / 0 / +1 octaves on sub out
* V / Oct tracking on 5 octaves (0V - 5V)
* CV (-5V - +5V) for wavetable modulation with attenuator
