From the project

Open-source drop-in PCB replacement for Google Nest Audio with Home Assistant integration

Open-source hardware replacement PCB for the Google Nest Audio smart speaker with Home Assistant integration.

This project provides a drop-in replacement PCB for the Google Nest Audio, converting it into a fully open-source Home Assistant voice assistant. The design is inspired by the nest-mini-drop-in-pcb project and follows the Home Assistant Voice Preview Edition hardware specification.

Nest audio: common questions

What microcontroller does the Nest audio use?

The Nest audio is built around the ESP32-S3R8, from the ESP32 family.

How many components are on the Nest audio?

1 components, from 1 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 Nest audio design files?

From the rauli2780/nest-audio-pcb repository on GitHub, which has the schematic and the BOM; the links under Design files point to each one.

Can I use the Nest audio design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which rauli2780 chose for the repository.

Can I test firmware for the Nest audio 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.
