Volume front panel: common questions

What microcontroller does the Volume front panel use?

The Volume front panel is built around the Pico, from the RP2040/RP2350 family.

How big is the Volume front panel PCB?

The Volume front panel measures 186.5 × 31.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Volume front panel?

33 components, from 18 distinct parts. The full bill of materials is listed on this page.

Where can I download the Volume front panel design files?

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

Can I use the Volume front panel design in my own project?

The repository has no license, so all rights stay with grahamseamans. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Volume front panel 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.
