Melody: common questions

What microcontroller does the Melody use?

The Melody is built around the XIAO-RP2040-SMD, from the RP2040/RP2350 family.

How big is the Melody PCB?

The Melody measures 85.4 × 69 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Melody?

4 components, from 4 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Melody design files?

From the Ka6667/Melody repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Melody design in my own project?

The repository has no license, so all rights stay with Ka6667. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Melody 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.
