MP3-Player: common questions

What microcontroller does the MP3-Player use?

The MP3-Player is built around the STM32F411CEU6, from the STM32 family.

How big is the MP3-Player PCB?

The MP3-Player measures 55 × 95 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the MP3-Player?

57 components, from 26 distinct parts. The full bill of materials is listed on this page.

Where can I download the MP3-Player design files?

From the rishub03/MP3-Player repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the MP3-Player design in my own project?

The repository has no license, so all rights stay with rishub03. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the MP3-Player without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
