Eurorack Synth Prototype

Lucian_dusk has created a self-described “functional Teensy 4.1-based breakout board for Eurorack modular synth(s).”

Based around the versatile Cirrus Logic CS42448 audio codec, the board features CV input and multichannel audio I/O, with an auxiliary PCB multiplexing five channels into one analog pin. More detail, including schematics, can be found in the original forum thread.
