Audio player: common questions

What microcontroller does the Audio player use?

The Audio player is built around the RP2040, from the RP2040/RP2350 family.

How big is the Audio player PCB?

The Audio player measures 74 × 63.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Audio player?

84 components, from 36 distinct parts. The full bill of materials is listed on this page.

Where can I download the Audio player design files?

From the Vaaarad07/PCB_Designs repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Audio player design in my own project?

Yes, under the terms of its MIT license, which Vaaarad07 chose for the repository.

Can I test firmware for the Audio player 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.
