Eurorack Noise / S&H Module

Len42·Synth·modules/Noise-SH/Noise-SH.kicad_pcb

Eurorack Noise / S&H Module is an open source PCB design by Len42: a 6-layer, 50.8 × 106.7 mm board with 70 components (50 distinct parts). It is built around the TL072, ICM7556, TL074. Filed under audio.

Eurorack synthesizer module designs

This module is built using the Delptronics Module Construction Set which includes PCBs for the front panel controls and other components. The PCB layout file is just a guide showing how I placed the components on the Delptronics boards. (It's a bit of a mess - sorry!)

Please note that I am a hobbyist, not a trained electronics engineer. No guarantees!
