About the MFOSmod PCB

MFOSmod is an open source PCB design by Micosilent, published on GitHub under the CC-BY-NC-4.0 license. It is a 2-layer board measuring 50 × 100 mm, with 102 components from 40 distinct parts.

Other key parts include the LM13700, TL072, OP275, TL074 and SSM2210. By type, the board carries 48 resistors, 15 capacitors, 11 connectors, 8 diodes, 7 ICs and 1 transistor.

It belongs with the audio designs in this gallery.

From the project

A transcription to KiCAD of Ray Wilson's synthesizer modules

This is a collection of modules from Ray Wilson's Music From Outer Space.

I will be using SMT in all the places I can, and replacing obsolete components that cant be found in the usual electronic distributors ( mouser or digikey ), with appropiate ones, following if possible Ray Wilson's advice on parts.

The idea is to end with all the modules from the supermodular bundle for starters, once we have all this modules we can look into transcripting other modules.
