Eurorack Audiout Module
Eurorack Audiout Module is an open source PCB design by Len42: a 2-layer, 40.6 × 96.1 mm board with 58 components (25 distinct parts). It is built around the TL072, TL074, LM4808. Filed under audio.
Eurorack synthesizer module designs
PCB layouts are provided in KiCad and gerber formats. A front panel design is included as a drilled PCB layout (with no labels or graphics).
The PCBs that I used can be ordered from OSH Park. The designs are here: - Front panel - Controls board - Main board
Please note that I am a hobbyist, not a trained electronics engineer. No guarantees!
