Muse Gadget open source meta SDK for DIY AI hardware devices – Unite.AI

Meta on October 2, 2026, open sourced device firmware and SDKs for building Muse gadgets, DIY hardware that connects the company’s Muse AI agent to displays, buttons, sensors, and actuators, and introduced Muse Home Link, a USB-C device that connects Muse to a home network, offered free to U.S. Muse subscribers while supplies last.

Nat Friedman announced the release in a post on It instructed builders to take an API token from the Muse Gadgets page and point a preferred coding agent to the project’s GitHub repository. Friedman said in a July 3, 2025 post that he started working at Meta that week, describing his work as creating artificial intelligence products that billions of people would like to use.

SDKs for open source devices

The SDKs and firmware reside in the facebookincubator/muse-gadget-sdk repository on GitHub, licensed with Apache 2.0, and provided as-is, without warranty. The repository is organized into esp32, linux, and skills directories, and each directory contains a README.md for starting builders plus an AGENTS.md file for coding agents like Muse Code.

The ESP32 Device SDK connects a standard ESP32 board to Muse, with options to add a screen showing images, incoming and outgoing audio, or other wired sensors. The Linux Device SDK turns a spare Raspberry Pi or Linux box into a Muse gadget, with support for custom commands; Repository examples include letting Muse handle system administration tasks or configuring Home Assistant.

Each gadget requires an SDK token to pair, and the repository instructs developers to review the gadget’s SDK Terms before flashing or pairing hardware. ESP32 and Linux gadgets pair with the Muse app on iOS and Android via Settings > Devices after the user turns on developer mode and appear with a “MuseGadget” prefix.

The Apache 2.0 license excludes several listed third-party files that retain their upstream licenses: the minimp3 header under CC0-1.0, an Adafruit GFX-derived pixel font file under the BSD-2 clause, the ESP-IDF components fetched at compile time, and the simulator LVGL and SDL libraries under their licenses. The license does not cover the Jollybot avatar. Meta frames the release as a just-for-fun project built by and for hardware hackers, warning that side effects of the tinkering could include bricked cards, voided warranties, brownouts or failures and telling builders to proceed at their own risk.

Muse home link

Meta has also created its own gadget. In a post on “We have produced a batch of 5,000 Home Links that should be ready to ship in a few weeks, and are free to Muse subscribers while supplies last,” he wrote, adding that all of the Home Link code is also open source.

According to the Meta page, community-developed skills can allow Muse to turn on a light, control a TV, or send a document to a printer, depending on the user’s setup. The terms of the application state that Home Link is free with an active US-only Muse subscription, limited to one per subscriber, and that units ship in October on a first-come, first-served basis. The claim occupies a place in the queue and is not an order; the process uses the applicant’s Muse account, and Meta says it will notify subscribers when the device is available for shipping.

Featured projects and builder community

The Muse Gadget page lists featured project ideas, most with purchase and source links. They include a Raspberry Pi 5 build that gives Muse a way to work with Home Assistant and other popular Linux applications; Waveshare ESP32-S3-Touch-AMOLED-1.75C, a 1.75-inch round AMOLED touchscreen with push-to-talk, speaker, microphone and battery; a dongle that plugs into the TV’s HDMI port so users can ask Muse to put things on the big screen, listed as coming soon; and Seeed reTerminal E1002, which gives Muse a color E Ink display that can show a morning briefing, reminder, or a shopping list.

Also listed are the pocket-sized M5Stack StickS3, with a color screen showing Muse status and a front button; the AiPi Lite, a little desk companion that responds aloud and displays images on a color screen when you press a button; an ideaspark ESP32 board with a 1.9-inch color display that shows Muse status and can draw images; and Home Assistant Voice Preview Edition, with push-to-talk via speaker and microphone and Muse status on an LED ring. Meta notes that the devices shown are made and sold by other companies and that it does not endorse or warrant them.

Builders can share finished projects in the Discord community’s #projects channel with a photo or short video, a line or two about the project, and a GitHub repository with a README file. Meta says there may be shared projects on the page, linked to their repositories so others can build them.
