This folder contains everything you need to land a routable PCB in KiCad without drawing the schematic by hand.

1. Install KiCad 8.x. 2. Add the Seeed library (only required because the XIAO ESP32-S3 isn't in KiCad's stock libs):

In KiCad: Preferences → Manage Symbol Libraries → Add ~/kicad-libs/seeed/Seeed Studio.kicadsym and Manage Footprint Libraries → Add ~/kicad-libs/seeed/Seeed Studio.pretty. 3. Create a new project here: File → New Project → save as pcb/esp-music-player.kicadpro. 4. Open the PCB Editor (the icon labelled "PCB Editor" / pcbnew). 5. Import the netlist: File → Import…

Esp32-music player battery: common questions

What microcontroller does the Esp32-music player battery use?

The Esp32-music player battery is built around the XIAO_ESP32S3, from the ESP32 family.

How many components are on the Esp32-music player battery?

13 components, from 12 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 Esp32-music player battery design files?

From the eriksalo/esp32-music-player-battery repository on GitHub, which has a netlist and the BOM; the links under Design files point to each one.

Can I use the Esp32-music player battery design in my own project?

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

Can I test firmware for the Esp32-music player battery 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.
