About the MUSIC-PLAYER PCB

MUSIC-PLAYER is an open source Nordic nRF PCB design by Ace6Rings, published on GitHub under the MIT license. It is a 6-layer board measuring 50 × 50 mm, with 93 components from 44 distinct parts.

Its main chip is the nRF5340-QKxx, from the Nordic nRF family. Other key parts include the SPX3819M5-L-3-3, MCP73831-2-OT, TPA6132A2RTE and PCM5102A. By type, the board carries 51 capacitors, 15 resistors, 7 ICs, 6 inductors, 5 connectors and 3 diodes.

It belongs with the audio and iot & wireless designs in this gallery.

Why did I build something like this? Well, I am sick and tired of buying spotify premium every month. I looked for mp3 players online but nearly all of them have the same flaw(s). They either have a very short battery life or they don't support bluetooth. This would mean that my headphones will last three times as long as a typical mp3 player. So, I solved all of these problems with my own music player.

The KiCad project lives in the Ace6Rings/MUSIC-PLAYER repository on GitHub; these links point at the commit this page was built from.

MUSIC-PLAYER: common questions

What microcontroller does the MUSIC-PLAYER use?

The MUSIC-PLAYER is built around the nRF5340-QKxx, from the Nordic nRF family.

How big is the MUSIC-PLAYER PCB?

The MUSIC-PLAYER measures 50 × 50 mm, has 6 copper layers and is 1.6 mm thick.

How many components are on the MUSIC-PLAYER?

93 components, from 44 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 MUSIC-PLAYER design files?

From the Ace6Rings/MUSIC-PLAYER 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 MUSIC-PLAYER design in my own project?

Yes, under the terms of its MIT license, which Ace6Rings chose for the repository.

Can I test firmware for the MUSIC-PLAYER without the hardware?

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