The EuroPi is a neat multi-functional eurorack module by Allen Synthesis, based on the Raspberry Pi Pico (and soon to be even better with Pico 2 support which should make it feel snappier !).

When I started sourcing parts to build one, I found that the OLED modules and buttons in the original design were a little more expensive for me to acquire in Australia, compared with the more common Ali Express versions. I also really wanted the design in KiCad. I reworked the EuroPi hardware to use these alternative OLED variants and cheaper tactile buttons. I also moved around some buttons and jacks to my own preferences (making it more like the uO_C Ornament and Crime layout).

This is the result - the screen is slightly offset to the left (which I’m guessing is why Rory Allen’s original design may have used less common OLED modules), so I’ve tried to maintain symmetry by ‘filling in’ the asymmetrical part with the silkscreen on the panel. I think it works okay (it’s not triggering any OCD in me anyway !).
