About the Attenuverter PCB

Attenuverter is an open source PCB design by gridbugs, published on GitHub under the MIT license. It is a 2-layer board measuring 71.9 × 168.7 mm, with 84 components from 12 distinct parts.

Other key parts include the TL074. By type, the board carries 40 resistors, 19 connectors, 8 diodes, 6 capacitors and 3 ICs.

From the project

A modular synthesizer, where modules are designed as close to bare PCBs as is practical/safe. This is the spiritual successor to the briefcase modular synthesizer.
