The Mecha Comet is made for hackers and makers
Quoting: Linux-powered handheld computer connects to Raspberry Pi HATs, snap-on modules —
Sure, your phone is fun, but if you want the fun and power of a full-fledged Linux computer in your pocket, you'll need to look elsewhere. The Mecha Comet is a 3.4-inch rectangular handheld that vaguely resembles a BlackBerry, but runs Debian Linux OS with a custom, touch-friendly UI on top. Launching soon on Kickstarter for $159, the device has a pogo pin interface where you can attach various extensions, including a gamepad, a Blackberry-style keyboard and a GPIO (General Purpose Input / Output) connector with 40 female pins.
Using the GPIO connector, you can attach a variety of electronic devices, including Raspberry Pi HATs. You can also attach HATs directly to the Comet or design your own extension board to attach to the pins.

Mecha Comet is a modular Linux handheld coming soon to Kickstarter for $159 - Liliputing
The Mecha Comet is a phone-sized computer small enough to slide into a pocket. But it has a smaller screen than most modern smartphones, runs a custom Linux-based operating system instead of Android or iOS, and features a modular design that lets you attach a keyboard, game controller, or other components to the lower half of the device.
You can’t actually buy one yet, but the makers of the Mecha Comet plan to launch a Kickstarter crowdfunding campaign soon with Early Bird rewards starting at $159.
Mecha Comet is a modular, handheld Linux computer with snap-on extensions
This is not a phone. The Comet by Mecha Systems is a modular, Linux-based handheld computer built for hobbyists, engineers, students, artists and roboticists of all kinds. The Comet is a chunky palm-sized device, and it has a 1.8 GHz ARM64 Quad-core processor, 4 GB of memory and 32 GB of on-board storage, though this space is expandable. Most of the Comet's features are customizable, in fact.
The Comet's magnetic snap interface allows users to clip on a variety of control panels, called extensions, transforming the handheld into whatever device you need. For now, Mecha offers three standard extensions: a gamepad with a soft-press D-pad and four input buttons, a GPIO panel with access to 40 pins, and a keyboard with ABS keys.

A Handheld Computer Free of Walled Gardens
Handheld computing is no longer a novelty with the meteoric rise in adoption of smartphone technologies in the past fifteen years. But while most of us now carry powerful computers with us everywhere we go, they are not really very good at being general-purpose machines. For starters, we can only install certain apps on them that a small number of gatekeepers allow in their app stores, which is quite limiting. Furthermore, there are precious few ways to interface with a phone. Take your pick — USB, wireless, or nothing.

I Was Never More Excited to Work and Play on This 3.4″ Display
This is where the Mecha Comet comes in. Displayed at CES 2025 but yet to be funded for manufacturing, it's essentially a pocket computer running Linux sporting a smartphone-like form factor with double the thickness—justifiably so for its excellent I/O (Input/Output) options. The front half of the device is expected to have a 3.4" LED touch-screen display, while the bottom half is completely modular with a magnetic snap to connect a physical QWERTY keyboard, a gamepad, or even a GPIO (General-Purpose Input/Output).
