Firmware complete, schematic ready, PCB coming soon. GitHub Repository

Core Principles

  • Zero Menu Diving. Every function accessible via direct hardware control
  • Simplicity. Do not overloaded by unnecessary features
  • DIY Friendly: Through-hole components only, open-source design

Key Features

  • 5 Independent Stereo Layers: 30 seconds each at 48kHz

Input

Hardware relay switching between input types:

  • Guitar (Hi-Z)
  • Microphone (preamp)
  • Stereo Line
  • Eurorack Input (WIP)

Controls

  • Volume: Individual + master
  • Speed: 0.3× to 2.0× per track (hold layer button + turn speed knob)
  • Pan: Real-time stereo positioning per track (hold layer button + turn speed knob)

Current Status

:white_check_mark: Firmware: Complete and tested
:white_check_mark: Schematic: Ready and tested
:construction: PCB: Work in progress - delivery soon!
:clipboard: BOM: Coming with PCB release

Why Open Source?

The DIY audio community thrives on shared knowledge and collaboration. By open-sourcing Ouroboros, I hope to:

  • Inspire new features: Community contributions and modifications
  • Build together: Foster innovation in the DIY music tech space

Get Involved

Hey @Alex_Kulinchenko!!

This sounds like a fun project!! Multi-input support (guitar, mic, and line) is great :slight_smile:
Definitely keep us posted as the hardware is coming together!

Thank you so much for sharing and also for making the project open source.

Hi Everyone,

Code is ready, prototype works well, time for PCB.

I’m at a crossroads now: should I go SMD or through-hole for the main components?

If SMD – what sizes would you feel comfortable soldering? (e.g., 0603, 0805, 1206)
If through-hole – any preferred part sizes or spacing for ease of assembly?

I’d love to hear what would make you most likely to actually build it once the PCB and code are ready.
Your feedback will help shape the design so it’s accessible and fun for as many people as possible.

Thanks!

I think for this project through-hole may be the way to go! The general consensus from what I can see is that it’s easier to solder.
