On October 2, 2026, Meta open-sourced the firmware and software kit for building hardware that connects to its Muse AI agent. The Muse Gadgets project gives any team the code to turn an ESP32 board or Raspberry Pi into a custom AI device.
What you can build this week
Grab a $20-50 board from any electronics supplier. An ESP32 works. So does a Raspberry Pi you already own. Download Meta's free firmware from GitHub, get a Muse account token, and you can build: a kitchen display that shows your day's schedule, a button that asks Muse to add tasks while you work, or an e-ink screen that updates your inventory count. Meta made 5,000 Home Link adapters — small USB devices that let Muse talk to your TV, printer, or smart lights — and gave them free to U.S. Muse subscribers while supplies lasted. Those shipped in October.
The code supports 11 ESP32 boards and any Linux computer with Bluetooth. A Discord community shares working examples.
What to keep in your hands
The hardware is yours. The firmware is open. But Muse itself still lives on Meta's servers. You need an active Muse subscription and a token Meta issues. If Meta changes the terms, raises the price, or shuts the token system, the gadget stops working. Build devices you can walk away from. Don't put your customer list, payroll data, or patient records into a Muse-connected device unless you have another way to retrieve them. The $50 board is yours to keep; the AI assistant it talks to is not.
