About the Disphaze Larger MCU Pads PCB

Disphaze Larger MCU Pads is an open source STM32 PCB design by dchwebb, published on GitHub under the Apache-2.0 license. It is a 2-layer board measuring 60 × 110 mm, with 78 components from 39 distinct parts.

Its main chip is the STM32F405RGTx, from the STM32 family. Other key parts include the MCP6004, TL072 and LM1117-3.3. By type, the board carries 26 resistors, 25 capacitors, 8 connectors, 4 ICs, 4 switches and 3 diodes.

It belongs with the audio designs in this gallery.

From the project

Eurorack Phase Distortion Oscillator module

Eurorack module providing two Phase Distortion oscillators based on Casio's CZ synthesizors.

Phase distortion involves warping a sine wave using a second phase distortion signal. The phase distortion tables in this module were loosely based on waveforms sampled from a Casio CZ-1000. Both oscillators allow the sine wave to be warped by a greater amount than on the original and in the case of oscillator 1 the phase distortion tables can be continuously varied.
