About the DeskMixer PCB

DeskMixer is an open source STM32 PCB design by RaduAndre, published on GitHub under the CC-BY-NC-4.0 license. It is a 2-layer board measuring 154.7 × 113.1 mm, with 96 components from 24 distinct parts.

Its main chip is the STM32F103C8T6, from the STM32 family. Other key parts include the C5116483, AMS1117-3.3, GD25Q64ESIG and SN74AHCT125DR. By type, the board carries 47 LEDs, 21 capacitors, 6 switches, 5 ICs, 5 resistors and 2 connectors.

It belongs with the displays & leds designs in this gallery.

From the project

DeskMixer is a software that allows control of application volumes with real sliders, and action mapping on buttons using arduino like platforms. The project was inspired originally by deej.

A low latency physical volume mixer with programmable buttons for Windows, inspired by Deej.

Control your audio with near-instant response and automate actions with real hardware - fully scalable to your needs!

DeskMixer: common questions

What microcontroller does the DeskMixer use?

The DeskMixer is built around the STM32F103C8T6, from the STM32 family.

How big is the DeskMixer PCB?

The DeskMixer measures 154.7 × 113.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the DeskMixer?

96 components, from 24 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 DeskMixer design files?

From the RaduAndre/DeskMixer 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 DeskMixer design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the DeskMixer 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.
