The DIY pedal builder’s map

From “what’s this chip?”
to “it’s done.”

Every DIY pedal PCB, mapped to the exact parts that build it — across PedalPCB, AION FX, and more. Start with a component; finish with a build.

From a single component to a finished pedal

Discover

Start with a chip you have or one you're curious about. Search it, and Pedal Builder lists every PCB project that uses it — with the matching component, the manufacturer parts that satisfy it, and the exact reference slots on each board. The classic “I have this chip, what can I build?”, answered instantly.

Plan

Favorite the boards you like and drop them in your cart. Pedal Builder merges their bills of materials into one aggregated parts list — every component, the quantity across all your builds, and which board each one is for — so you can shop for several projects in a single order.

Stock

Log what's actually in your drawers. Filter the parts catalog by type, sort resistors by value, and add quantities to your inventory in a click. Your inventory becomes the source of truth for what you can build right now.

Build

Open a build and work the bench: every reference slot shows its component, the part you've chosen, and what you've installed — drawn straight from your inventory. Move it from partial to complete, add notes and photos, and always know exactly where a build stands.

Share

Finished it? Make the build public and it lands in the community gallery — cover photo, status, and builder — for everyone to browse. See what other people are making, and show off your own.

Common questions

Do I need an account to search?

No. The full search index, every component, every PCB, and every BOM is publicly browsable.

What does an account get me?

Favorites and a shopping cart that aggregates a BOM across multiple PCB projects.

What's premium for?

Real-world tracking: inventory of parts and blank PCBs, "what can I build right now?" suggestions, and per-build status tracking.

Where does the data come from?

Public PCB project documentation: PedalPCB, AION FX, Madbean, and others. Every BOM line is mapped to a normalized component record.
