Deftaudio have created a neat solution for those looking to integrate a Raspberry Pi with their modular setup. It features a 5" screen, with ports for MIDI, audio and USB connections - enabling you to run audio units using the micro computer without the need to leave your rack. It utilizes a Synth Kit I/O::module to interface with Eurorack power, audio, and MIDI - and comes with a wealth of supporting documentation.
They've also created an assembly guide for a full run down of getting it going:
