Meta open-sources Muse Gadgets so you can put Muse on DIY hardware

Meta on Friday published Muse Gadgets — open-source ESP32 and Linux device SDKs (Apache 2.0) so people can build their own Muse-connected hardware — and opened a claim list for Muse Home Link, a USB-C home-network dongle Meta says it manufactured in a batch of 5,000.

Muse was already Meta's bet that an agent belongs on a keychain and glasses. Shipping open SDKs plus a free Home Link batch is the ecosystem play — seed enough DIY endpoints that Muse stops being a single gadget and starts looking like a house-wide agent fabric.

On Friday, 2 October 2026, Meta published Muse Gadgets. The page is gadgets.muse.ai. The title is “Muse Gadgets: Open source hardware for your Muse.” The headline is “Open source hardware for your Muse.” The page does not print an hour. Muse, here, is Meta’s personal AI agent, the software a person can hand tasks to. A gadget, on this page, is a device you build yourself. The opening line says to program an off-the-shelf ESP32 board or set up a Raspberry Pi with Meta’s SDKs, then connect Muse to displays, buttons, sensors, actuators, and whatever else is on the workbench. An ESP32 is a small cheap board with a radio, the kind hobbyists use for sensors and tiny screens. A Raspberry Pi is a small Linux computer about the size of a deck of cards. An SDK, a software development kit, is the code and instructions for making that hardware talk to Muse. A sensor reads the world, like a button or a microphone. An actuator does something physical, like turning a motor. Those lines are Meta’s, on the page.

What Meta says it open-sourced, and the warning next to it. The page says Meta open-sourced the code you need to make a Muse gadget, “built by hackers, for hackers, just for fun.” It says side effects of tinkering may include bricked boards, voided warranties, brownouts, or bankruptcies, and to proceed at your own risk. A bricked board is one that will no longer start. A voided warranty means the maker of that board may refuse a repair. A brownout is a dip in power that can crash the board. Bankruptcies is Meta’s joke on the same line. The start, the page says, is an SDK token and one of the featured project ideas, then tinker, or build support for an entirely new board. An SDK token is a key from a Muse account that lets the device sign in. Those lines are Meta’s.

The two kits. The ESP32 Device SDK connects an ESP32 board to Muse. The page says to throw in a screen to show images, add audio in and out, or wire up other sensors. The Linux Device SDK turns a spare Raspberry Pi or other Linux box into a Muse gadget. The page says you can hack in your own commands so Muse can handle sysadmin chores or a Home Assistant setup. Sysadmin chores, here, are the upkeep jobs on that computer. Home Assistant is a widely used program for controlling lights, speakers, and other devices in a house, usually running on a machine you own. Those lines are Meta’s, on gadgets.muse.ai. The page links the code to a GitHub repository, facebookincubator/muse-gadget-sdk, with an ESP32 folder and a Linux folder.

The license, in the page’s own sentence. “The device SDKs and firmware are open source under the Apache 2.0 license and provided as-is, without warranty.” Firmware is the program that lives on the board. Open source means the code is public and people can change it. Apache 2.0 is a license that lets someone use, change, and share that code, including in a product they sell, if they keep the license notice and state what they changed. As-is, without warranty, means Meta is not promising the code will work, and is not promising to fix a board it breaks. The page says to use the code as a starting point and contribute improvements back. Those lines are Meta’s.

The project ideas Meta prints, and who makes the boards. A section headed “Project Ideas” names eight examples. A Raspberry Pi 5, the page says, gives Muse a way to work with Home Assistant and other popular Linux applications. A Waveshare ESP32-S3-Touch-AMOLED-1.75C is “a round 1.75″ AMOLED touch screen with push-to-talk, a speaker and mic, and a battery.” AMOLED is a bright color screen. Push-to-talk means you hold a button while you speak. “Muse on your TV” is “a stick that plugs into your TV’s HDMI port so you can ask Muse to put things up on the big screen,” and that card is marked coming soon. HDMI is the video plug on the back of a television. A Seeed reTerminal E1002 is a color e-ink display. E-ink holds a picture with almost no power, the way a Kindle does. The page says Muse can show a morning briefing, reminders, a shopping list, or anything else you think of. An M5Stack StickS3 is “a pocket-size M5Stack device with a color screen showing Muse’s status and a front button.” An AiPi Lite is “a tiny desk buddy.” You press a button to talk, and Muse answers out loud and shows pictures on the color screen. An ideaspark ESP32 with a 1.9-inch display is a status screen: see what Muse is doing, and let it draw on that small color display. A Home Assistant Voice Preview Edition lets you talk to Muse with push-to-talk on its speaker and mic, and see status on an LED ring. An LED ring is a circle of small lights. Under the list, Meta says the devices shown are made and sold by other companies, and Meta does not endorse or warrant them. Names and logos belong to their owners. Those lines are on gadgets.muse.ai. The page does not print a Meta price for any of those boards.

How The Verge and Engadget retell those ideas, still on Friday. Jay Peters, The Verge, 2 October 2026, 9:08 p.m. UTC, which is 5:08 p.m. Eastern, says Meta now lets you make your own Muse gadgets with code the company open-sourced. He names three suggestions: a color e-ink display that shows reminders, an HDMI stick so Muse can appear on a big screen, and a small touchscreen that “looks kind of like a DIY Muse Charm.” Charm is Meta’s own handheld for Muse, a separate product. DIY means do it yourself. Peters quotes the workbench line from the gadgets page and the “proceed at your own risk” caution. Karissa Bell, Engadget, 2 October 2026, 4:27 p.m. Eastern, says Muse Charm will not be the only dedicated hardware for the agent. She says Nat Friedman, head of product for Meta’s Superintelligence Labs, described open-source firmware and a Linux SDK that let people bring the agent to hardware. She names a dedicated e-ink display, an HDMI dongle for a TV, and a small touchscreen accessory that “looks a bit like the Muse Charm itself.” A dongle is a small stick that plugs in. She says Meta started a Discord community for the project. She also writes that Mark Zuckerberg revealed Muse Charm last week at Connect, and that he said it could be a good alternative for people who want to talk to the agent without wearing Meta’s smart glasses. That is Engadget’s sentence. Neither piece prints a Charm price, a Charm ship day, a count of Muse subscribers, or a revenue figure.

The gadget Meta says it made: Muse Home Link. On gadgets.muse.ai the section is “One we made: Muse Home Link.” It connects Muse to home Wi-Fi so Muse can reach compatible devices a person already owns, or anything they build that exposes a local HTTP API. An HTTP API, here, is a web address on the home network that another program can call. Community-built skills can let Muse turn on a light, control a TV, send a document to a printer, and more, depending on the setup. A skill, on this page, is a small program the community wrote for one kind of device. The same paragraph is on the Home Link page at gadgets.muse.ai/home-link. Those lines are Meta’s. The gadgets page does not print the number 5,000 in that text.

What the Home Link page says the puck is. It is a USB-C gadget built on the ESP32-C5 chip. USB-C is the oval plug on recent phones. The page says the firmware is based on the open-source ESP32 Device SDK, so a person can see how it works and build their own gadget on an ESP32 board. It also says Muse Home Link itself only runs official firmware and cannot be reflashed. Reflashed means writing a different program onto the chip. The claimed puck stays on Meta’s software. A homemade board is the separate path. The spec table lists an Espressif ESP32-C5, a 32-bit RISC-V chip at 240 MHz, 8 MB of PSRAM, 8 MB of flash, Wi-Fi 6 on 2.4 and 5 GHz, a USB-C and a USB-A connector, an LED for pairing and device status, and dimensions of 35 by 42 by 10 millimeters. RISC-V is an open design for the instructions a chip understands. 240 MHz is the clock: about 240 million ticks a second. PSRAM is extra working memory. Flash is the storage the program sits in. Eight megabytes is small. One phone photo is often that large. Wi-Fi 6 is the common newer home wireless standard, and the page says this radio uses both the 2.4 GHz and 5 GHz bands. USB-A is the older rectangular USB plug. Thirty-five by 42 by 10 millimeters is about 1.4 by 1.7 by 0.4 inches. That inch line is arithmetic on Meta’s millimeters. The page does not print inches. Those lines are on the Home Link page.

How Meta says you set it up, and what the skills are allowed to be. Plug Home Link into any USB-C or USB-A power source near the router. Add the device in the Muse app. Setup runs over Bluetooth LE, and you choose the Wi-Fi network Home Link joins. Bluetooth LE is the low-power radio phones use for pairing, not the Wi-Fi the device stays on. Once it is on the network, Muse can reach the devices. The page says community skills cover popular integrations such as Philips Hue, Sonos, Apple TV, Google Nest speakers, and Samsung TVs, installed from the skills folder in the same GitHub repository. It says skills are built by the community, so they can change or break. “Have fun with them, but don’t rely on them for anything safety-critical like home security, emergencies, or medical needs.” That sentence is Meta’s. The page repeats that devices mentioned are made and sold by other companies, and Meta does not endorse or warrant them.

Who gets one, and whose sentence the batch of 5,000 is. The gadgets page and the Home Link page both say: “Free with an active Muse subscription in the United States only, limit one per subscriber. Ships in October, first come, first served.” The claim box says it is available to Muse subscribers in the United States, that Meta will notify you when Home Link is available to ship, and that claiming holds your place in line and is not an order. It uses the Muse account, and you log in first if needed. The page does not print a dollar price. The page does not print how many subscribers Meta has. The batch size is Nat Friedman’s. The Verge says Meta manufactured 5,000 of the gadgets, according to Nat Friedman of Meta Superintelligence Labs, and that people can claim a waitlist spot ahead of shipping sometime this month. Engadget quotes his post: Home Link is “a little usb-c powered device that allows Muse to connect to your home network to talk to smart home devices like TVs and speakers and anything else that exposes https,” and “We manufactured a batch of 5000 Home Links.” Https, in that line, is the secure form of a web address. Engadget says Meta is giving 5,000 of them to Muse subscribers. Five thousand is his figure, as those two pieces report it. It is one batch, not a promise of a second run.

Where the builders are supposed to talk. The gadgets page says to meet other people building and customizing Muse gadgets in a community Discord, to get inspired, support each other, and share what you make. Discord is a chat app. A section on sharing says: made a Muse gadget, share it in #projects on Discord, and Meta may feature it, linked to your repository so others can build it. Before you post, the page asks for a photo or short video, a line or two about the project, and a GitHub repository with a README ready. A README is the first page of notes in a code project. Those lines are Meta’s. The page shows a live count of people online in that Discord. That count moves. It is not a membership total.

The picture is Meta’s Muse Gadgets card on a dark charcoal field. The top reads Muse Gadgets, Build your own, and Open it up. A cream puck in the center is labeled Muse Home Link, with lines for USB-C, 5,000 made, and U.S. subscribers. Around it sit a round Waveshare ESP32 board, a green Raspberry Pi, a small M5Stack board, and a Seeed Studio e-ink display. A line under the devices reads Apache 2.0 and ESP32 and Linux SDKs. A bottom row reads lights, TVs, printers, and Home Assistant. The frame does not print a calendar date. It is a lineup card. It is not a photograph of a living room, and it is not a picture of Muse Charm.

In plain terms, Meta on Friday published the code for people to put Muse on hardware they build: an ESP32 board or a Raspberry Pi, under an Apache 2.0 license, with no warranty, and with a warning that tinkering can kill a board. The examples on the page include a color e-ink reminder screen, a round touchscreen, a pocket status display, Home Assistant on a Pi, and an HDMI stick for a TV that Meta marks as coming soon. Those boards are other companies’ products. Separately, Meta is offering Muse Home Link, a small USB-powered puck on an ESP32-C5 that stays on the home network so Muse can reach lights, TVs, printers, and other devices through community skills. Those skills can break, and Meta says not to trust them for security, emergencies, or medical needs. The puck itself runs only Meta’s firmware. A claim holds a place in line for U.S. subscribers, one each, free with an active Muse subscription, shipping in October, first come, first served. It is not an order. Nat Friedman’s figure for the batch, as The Verge and Engadget report it, is 5,000.
