From the project

Demiurge is a combination of Hardware and Software for Digital Sound Processing in the Eurorack Modular Synthesizer environment.

Demiurge is a combination of Hardware and Software for Digital Sound Processing in the Eurorack Modular Synthesizer environment.

The "Demiurge 1" board is an 8 HP Eurorack compatible board, the functionality defined in software and custom front panel can either be made by hand, ordered from local mechanical shops or ordered from PCB manufacturers (KiCad template for front panel exists).

Demiurge: common questions

What microcontroller does the Demiurge use?

The Demiurge is built around the CH32V307RCT6, from the RISC-V family.

How big is the Demiurge PCB?

The Demiurge measures 40.1 × 109.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Demiurge?

151 components, from 46 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Demiurge design files?

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

Can I use the Demiurge design in my own project?

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

Can I test firmware for the Demiurge without the hardware?

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