This is a module for a modular synthesizer, also useable as a standalone-gear.

It uses an USB-C-input to create an USB-MIDI-connection with a computer, tablet or smartphone. It can create 8 different voltages between 0 and +5V to control a synthesizer (like Behringer Kobol or others).

The Software for the ESP32-S3-WROOM is available for free on Github

You need to printout the knobs from stl-file available there.

You will need M3-screws of different length, 14mm and 4mm, nuts M3, some of them.

Chip-programming:

The module has two USB-connections. The upper-one is for programming the interface, the lower for USB-MIDI-connection.

You need to set the correct settings to get Tiny-USB working. An image showing the settings is available on my Github-repository.

Needed Libraries (you can choose the libraries and install them directly inside Arduino IDE, don't need to use Git-functions) :

PS: The shown Eurorack-wood-case is an IKEA-Hack.

Its an IKEA Tavelan-box. Tavelan can be found at IKEA in the bathroom-store. It is made of two boxes, one big (thats used here) and a small one. Both can be used to hold Eurotrack-Modules. The rails for the boxes can be downloaded at Thingiverse.
