About the Poly UA controller 5enc 5sw PCB

Poly UA controller 5enc 5sw is an open source PCB design by PhysicsDptAngers, published on GitHub under the MIT license. It is a 2-layer board measuring 139.2 × 49.3 mm, with 26 components from 8 distinct parts.

Other key parts include the MCP23017_SO. By type, the board carries 8 resistors, 6 capacitors, 5 switches, 5 diodes, 1 IC and 1 connector.

It belongs with the audio designs in this gallery.

From the project

Open source, analog and polyphonic synthesizer

The controller board serves as the equivalent of a synthesizer’s front panel.

For now, we provide a very basic frontend for a subtractive synthesizer. It is more of a demonstration of what can be done than a de facto standard. You can, in principle, design any frontend you like.

The controller board must send its data in MIDI format over the I²C bus to the conductor board.
