About the DisPhaze PCB

DisPhaze 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.

DisPhaze: common questions

What microcontroller does the DisPhaze use?

The DisPhaze is built around the STM32F405RGTx, from the STM32 family.

How big is the DisPhaze PCB?

The DisPhaze measures 60 × 110 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the DisPhaze?

78 components, from 39 distinct parts. The full bill of materials is listed on this page.

Where can I download the DisPhaze design files?

From the dchwebb/DisPhaze repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the DisPhaze design in my own project?

Yes, under the terms of its Apache-2.0 license, which dchwebb chose for the repository.

Can I test firmware for the DisPhaze without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
