A kid-friendly jukebox powered by the ESP32

A kid-friendly jukebox powered by the ESP32, inspired by Phoniebox. Unlike the original Raspberry Pi–based version, phoniesp32 is designed to be battery-operated, low-power, and ultra-portable.

Phoniesp32: common questions

What microcontroller does the Phoniesp32 use?

The Phoniesp32 is built around the ESP32-C6-WROOM-1U-N4, from the ESP32 family.

How big is the Phoniesp32 PCB?

The Phoniesp32 measures 57.4 × 50 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Phoniesp32?

55 components, from 32 distinct parts. The full bill of materials is listed on this page.

Where can I download the Phoniesp32 design files?

From the butzist/phoniesp32 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Phoniesp32 design in my own project?

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

Can I test firmware for the Phoniesp32 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
