Overview
Modules is an open-source printed circuit board by michd, from the michd/modular-synth repository on GitHub. It is a 2-layer board of 58.9 × 89.1 mm with 69 parts on 50 nets, routed with 436 tracks and 0 vias.
It is built around the LM13700M and LM386. Its parts include 34 resistors, 18 capacitors, 9 connectors, 4 ICs and 2 diodes. It belongs with the audio and music boards of this library.

README.mdModular Synthesizer
My fiancee and I plan to build a modular synthesizer, for fun. Here's a repository to hold all kinds of stuff to do with that. I imagine it'll hold the following
- Schematic designs
- PCB designs derived from those schematic design
- Some 3D modeling for related hardware
- Any microcontroller code

Questions
How big is the Modules PCB?
It measures 58.9 × 89.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Modules use?
69 parts, built around the LM13700M and LM386. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Modules KiCad files?
From the michd/modular-synth repository on GitHub, at the commit this page was made from: the board is modules/reverb/kicad/reverb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Modules design in my own project?
Its repository states no licence, so its author keeps all rights: ask michd before reusing the design.
