The Mecha Comet, a palm-sized modular Linux computer, has launched on Kickstarter, emphasizing adaptability through snap-on modules. This open-source device caters to tinkerers and enthusiasts with customizable hardware and a Fedora-based operating system. It has already raised over $500,000 in funding shortly after its campaign began.
Linux handheld devices are gaining popularity, and the Mecha Comet stands out for its modular design and open-source ethos. Developed by the Mecha team over several years, this real prototype— not just a concept—features a 3.92-inch AMOLED touch display with 550 nits brightness and 441 pixels per inch, making it suitable for portable use without aiming to replace phones or laptops.
The device offers two ARM-based configurations: a base model with a 4-core NXP i.MX 8M Plus processor, and a premium version with a 6-core i.MX 95 that doubles GPU performance but reduces battery life by about 15%. It includes a replaceable 4100mAh battery rated for 7 hours of active use or 7 days in suspend mode. Memory options range from 2GB to 8GB RAM, with 64GB to 128GB eMMC storage, expandable via MicroSD or M.2 SSD slots.
Connectivity is robust, with mini HDMI 2.1, an 8MP autofocus camera, dual microphones, an HD speaker, a 3.5mm audio jack, two USB-C ports, Wi-Fi 5, Bluetooth 5.4, and a physical SIM slot. Onboard sensors and a Trust Anchor (CC EAL 6+) enhance security.
Adaptability comes from three magnetic snap-on modules using a 40-pin connector: a gamepad with D-Pad and buttons for gaming, a GPIO header for tinkering with I/O breakout and serial over USB, and a QWERTY keyboard with touchpad for productivity. The hardware is open-source under the CERN-OHL-S-2.0 license, including PCB schematics and 3D files, allowing users to create custom expansions. The keyboard is QMK-compatible and user-serviceable.
Running Linux kernel 6.12 and U-Boot, it uses a Fedora-based Mechanix OS with a touch-optimized Wayland GUI built in Rust. The interface supports multitasking, a login screen, app launcher, and settings customization. Native apps are developed in a Flutter-based Dart toolkit, and users can install ARM-compatible software from Fedora repositories, though the small screen limits some applications.
Pricing starts at $189 for the early bird base model (i.MX 8M Plus, 2GB RAM, 64GB storage), rising to $269 for the premium (i.MX 95, 4GB RAM, 64GB). Modules cost $15 for GPIO, $20 for gamepad, $25 for keyboard, or $50 bundled. RAM upgrades add $30 or $60. Shipping fees range from $18 to $40. Base models are slated for May/June 2026, with premium versions following in September 2026. The Kickstarter campaign, live as of January 26, 2026, has quickly surpassed $500,000 in pledges.
