Overview
MostlyBuildsSpeakerPodLight is an open-source printed circuit board by MostlyBuilds, from the MostlyBuilds/speaker-pod-light-pcb repository on GitHub, published under the CC-BY-SA-4.0 licence. It is a 2-layer board of 79 × 79 mm with 13 parts on 6 nets, routed with 28 tracks and 20 vias.
Its parts include 4 resistors, 4 diodes and 1 connector. It belongs with the audio and music boards of this library.

Build Resources
- Order the Light Pod PCB through PCBWay - the board is available through the PCBWay Project Hub.
- Download the speaker's 3D models on MakerWorld - enclosure models for the complete Retro Smart Speaker V2 build.
- Read the V2 build article - build details and the complete current parts list.
- Main Speaker Pod PCB - design files for the controller and audio board that connects to the Light Pod.
Hardware Notes
- The Light Pod connects to the main Speaker Pod PCB and mounts at the bottom of the enclosure.
- Its LEDs illuminate the surface beneath the speaker to create a halo effect.
- Manufacturing note: I used a 1 mm thick PCB instead of the common 1.6 mm thickness. Vertical clearance is tight in the Speaker Pod enclosure, so check your enclosure before ordering.
Opening The Project
Open MostlyBuildsSpeakerPodLight.kicad_pro in KiCad.
These files use KiCad 7 format markers (kicad_sch version 20230121, kicad_pcb version 20221018). Use KiCad 7 or newer unless you intentionally migrate the design.
Manufacturing Outputs
Generated fabrication outputs are not committed here. Plot Gerbers, drill files, and any assembly documentation from KiCad after reviewing the current schematic, PCB layout, design rules, and fabrication requirements.
Disclaimer
This project is provided as-is by a hobbyist. Review the design carefully and use your own judgment before building, modifying, or manufacturing it.

Questions
How big is the MostlyBuildsSpeakerPodLight PCB?
It measures 79 × 79 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MostlyBuildsSpeakerPodLight use?
13 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the MostlyBuildsSpeakerPodLight KiCad files?
From the MostlyBuilds/speaker-pod-light-pcb repository on GitHub, at the commit this page was made from: the board is MostlyBuildsSpeakerPodLight.kicad_pcb and its schematic MostlyBuildsSpeakerPodLight.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MostlyBuildsSpeakerPodLight design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
