Meta open-sourced the firmware and device SDKs for Muse gadgets on October 2, 2026, allowing hardware developers to connect the company’s Muse AI agent to physical displays, buttons, sensors, and actuators.
Hardware Developer Kits and Repository Architecture
The SDKs and firmware reside in the facebookincubator/muse-gadget-sdk repository on GitHub under an Apache 2.0 license, provided as-is without warranty. The directory structure splits into esp32, linux, and skills folders, each containing a README.md file and an AGENTS.md file tailored for coding agents like Muse Code. The ESP32 Device SDK links off-the-shelf ESP32 boards to Muse, supporting screens for images, audio input and output, and wired sensors. Meanwhile, the Linux Device SDK turns Raspberry Pi units or standard Linux computers into Muse gadgets equipped for custom commands, such as managing system administration tasks or handling Home Assistant setups.
Every hardware build requires a unique SDK token for pairing. Developers must review the Gadget SDK Terms before flashing or pairing devices. ESP32 and Linux hardware connect with the Muse app on iOS and Android devices under Settings > Devices once users enable Developer mode, identifying themselves with a “MuseGadget” prefix. The Apache 2.0 license explicitly excludes several third-party components that retain their original licenses, including the minimp3 header under CC0-1.0, an Adafruit GFX-derived pixel font under BSD-2-Clause, build-time ESP-IDF components, and the simulator’s LVGL and SDL libraries. The Jollybot avatar is also excluded from the open-source license.
Muse Home Link Hardware and Distribution
Meta manufactured a batch of 5,000 Muse Home Link units as an official hardware accessory. Friedman introduced the device on X as a small, USB-C powered unit that bridges Muse to home networks, enabling interaction with smart TVs, speakers, and any hardware exposing a local HTTPS API. Meta offers the Home Link hardware for free to active U.S. Muse subscribers while supplies last, limiting claims to one per subscriber on a first-come, first-served basis. The ordering process utilizes the user’s Muse account to hold a place in line, and all Home Link code is open source.
Community-built skills allow the system to execute tasks like turning on lights, controlling televisions, or sending documents to printers based on individual user configurations. Meta states that tinkering with the open-source firmware carries inherent physical risks, warning that side effects may include bricked boards, voided warranties, brownouts, or bankruptcies, advising builders to proceed at their own risk.
Featured Project Ecosystem and Third-Party Displays
The Muse Gadgets documentation highlights multiple third-party hardware projects designed to work with the ecosystem. Featured builds include a Raspberry Pi 5 integration for Home Assistant applications and the Waveshare ESP32-S3-Touch-AMOLED-1.75C, a round 1.75-inch AMOLED touchscreen featuring push-to-talk capabilities, an integrated speaker, a microphone, and a battery. Additional projects feature an upcoming HDMI stick for displaying content on big screens, the Seeed reTerminal E1002 color E Ink display for morning briefings and shopping lists, the pocket-sized M5Stack StickS3 with a status screen and front button, the AiPi Lite desk companion, an Ideaspark ESP32 board with a 1.9-inch color display, and the Home Assistant Voice Preview Edition utilizing an LED ring for status updates.
Frequently Asked Questions
What licensing terms govern the Muse Gadgets repository?
The firmware and SDKs are licensed under the Apache 2.0 license, though certain third-party files retain their original licenses, such as the minimp3 header under CC0-1.0 and specific LVGL and SDL libraries.
How do developers pair custom hardware with the Muse application?
Developers must generate an API token from the Muse Gadgets page, flash their ESP32 or Linux hardware, enable Developer mode in the Muse iOS or Android app, and pair the device under the Settings > Devices menu.
Who is eligible to claim a free Muse Home Link device?
Active U.S. Muse subscribers can claim one free Home Link unit on a first-come, first-served basis while supplies last from the initial batch of 5,000 manufactured devices.
