The Plinky Expander 2HP adds extra functionality when using your Plinky in a Eurorack system.

This expander adds four additional CV outputs to connect with the rest of your Eurorack setup, as well as a frontside USB-C port and TRS MIDI allowing for access these ports when Plinky is rack mounted.

• TRS MIDI Input: Supports both Type A (Korg) and B (Arturia)
• TRS MIDI Output: Supports Type A (Korg)
• USB C: Edit patches and interface with MIDI over USB, and update Firmware with Plinky in the rack. Note that you can not power Plinky from this port.
• A B X Y Outputs: Output Plinky‘s A B X Y modulation as CV

The 2HP Expander is an updated revision of the classic 4HP DIY Plinky Expander, now available as a factory-built and tested module offering the same features in a more compact form factor.

This version is compatible with Plinky v3 (black) and Plinky v2 (blue). For compatibility with Plinky v1 (green), you have to do a modification on your Plinky Expander port as described in the docs.
