HSP-Protoseed PCB - Daisy Seed Pedal Prototype platform

HSP-Protoseed PCB

Your ticket to easy, in-house DSP pedal prototyping. The HSP-Protoseed is a Canadian-made, CNC-milled prototyping board for the Daisy Seed that gives you a ready-to-go hardware platform for testing, tweaking, and releasing your own digital effects.

Designed around the Harold Street Pedal Company’s v1.2 control layout, it’s fully mapped for six pots, four toggles, two LEDs, and two footswitches — all neatly tied into our open-source HaroldPCB Arduino library. That means you can start writing pedal code without touching low-level DaisyDuino setup.

What you get:

CNC-milled PCB, made in Canada, drilled and ready for assembly.

Full compatibility with Daisy Seed audio I/O.

GitHub repo with library, quick start, and beginner-friendly lessons.

What you don’t get:

Components — you’ll need your own pots, switches, jacks, LEDs, semiconductors, and passives.

Daisy Seed controller — bring your own brain.

Perfect for beginners, powerful enough for pros. Whether you’re cooking up a warped VHS dream machine, a gritty lo-fi delay, or your own ghost-voiced reverb, the HSP-Protoseed PCB is your blank canvas. Load up the library, flash your code, and hear your ideas come to life!
