Building the EuroPi Module

If you're a fan of Eurorack synthesizers and the Raspberry Pi, the EuroPi module might be right up your alley. Developed by Rory Allen and a group of talented contributors, the EuroPi is a reprogrammable module for Eurorack that uses the Raspberry Pi Pico mini PC as a base. It's a versatile and affordable option for anyone looking to create their own Eurorack synthesizer module from scratch using MicroPython.

When I first started building my Eurorack setup, I was frustrated by the cost of individual utilities and the fact that I didn't need most of them for any given patch. Recently I discovered the EuroPi. It's a great way to prototype and experiment with different ideas without breaking the bank. Plus, it's all open-source, so you can tweak it to your heart's content.

Getting Started

Building the EuroPi module is relatively straightforward, even if you don't have much experience with DIY electronics. You'll need a Raspberry Pi Pico and a few other components, such as LEDs, buttons, and knobs. You can find a complete list of parts and instructions on the EuroPi GitHub page.

Once you have everything you need, it's just a matter of following the step-by-step instructions. I found the process to be very user-friendly, even as a beginner. There are also helpful photos and diagrams to guide you along the way.

Benefits of the EuroPi

One of the main benefits of the EuroPi is its versatility. Because it's reprogrammable, you can customize it to suit your needs. Whether you're building a sequencer, a filter, or a sample player, the EuroPi can handle it all. Plus, because it's based on the Raspberry Pi Pico, you have access to the entire MicroPython library, which is a great resource for anyone interested in programming.

Another benefit of the EuroPi is its affordability. Building a Eurorack setup can be an expensive hobby, but the EuroPi module is a cost-effective way to experiment and prototype. Plus, because it's open-source, you can share your creations with the community and get feedback from other enthusiasts.


Overall, I highly recommend the EuroPi module for anyone interested in building their own Eurorack synthesizer modules. It's a versatile, affordable, and easy-to-use option that will help you bring your ideas to life. Whether you're a beginner or an experienced DIY electronics enthusiast, the EuroPi is a great tool to have in your arsenal.
