RP2040 Audio

Maker	Eric Brombaugh
Type	Stereo audio effects module built on the RP2040 with a WM8731 codec
Mounting	SMD
Width	8 HP
License	Proprietary (MIT covers the code, no hardware grant)
Difficulty	🌋 Fine-pitch SMD

Two CV inputs, stereo audio in and out, and a PCB front panel. The README is written as a feasibility study of the RP2040 for demanding DSP. No gerbers are published.
