About the Nest audio PCB

Nest audio is an open source ESP32 PCB design by spandit69, published on GitHub under the CERN-OHL-S-2.0 license. It is a board, with 1 components from 1 distinct parts.

Its main chip is the ESP32-S3R8, from the ESP32 family.

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

From the project

🔊 Replace your Nest Audio PCB with an open-source, Home Assistant-friendly board featuring ESP32-S3 and XMOS DSP for advanced voice control.

nest-audio-pcb is an open-source printed circuit board (PCB) designed to replace the original PCB inside Google Nest Audio speakers. This replacement board includes Home Assistant integration, making it easier to control your smart speaker within your home automation setup.

If your Google Nest Audio device is no longer working, or if you want to upgrade its capabilities with an open-source solution, nest-audio-pcb provides a direct swap. It fits right into your Nest Audio’s casing and works with the existing speakers and hardware.

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 spandit69/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 spandit69 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.
