Pedalboard hw: common questions

What microcontroller does the Pedalboard hw use?

The Pedalboard hw is built around the RP2040, from the RP2040/RP2350 family.

How big is the Pedalboard hw PCB?

The Pedalboard hw measures 174 × 111 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pedalboard hw?

142 components, from 55 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pedalboard hw design files?

From the pedalboard/pedalboard-hw repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Pedalboard hw design in my own project?

Yes, under the terms of its CERN-OHL-P-2.0 license, which pedalboard chose for the repository.

Can I test firmware for the Pedalboard hw without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
