The YGN Framework

Three parts. One repeatable platform.

Sets a repeatable mechanical format for fabrication and assembly.

Handles power, true-bypass switching, and every external connection.

Keeps the audio circuit focused on sound within a standard footprint.

Proven effect circuits built on the YGN Framework

An 18V Power Boost-derived drive built around the clean-to-dirty transition, with a master volume.

Our reference design: a RAT-derived distortion with Sweep control and selectable clipping.

Step-by-step guides for building with the YGN Framework

Prepare a UPDI programming connection, flash your YGN IO Board and check its operation using the Small IO Board as a worked example.

Set up the dedicated YGN FV-1 EEPROM programmer for use with SpinASM for VS Code.

Set up a 3.3 V Arduino Pro Mini to program FV-1 EEPROMs with SpinASM for VS Code.
