A new crowdfunding campaign for the RootBoard offers a compact, battery-powered portable terminal for Raspberry Pi Zero users. This project matters to tinkerers who want a dedicated pocket-sized Linux device with a full 70-key keyboard. The shell transforms a low-cost single-board computer into a self-contained unit with a built-in battery and integrated speakers.
Compact shell adds display and keyboard to low-power single-board computer
Dian Lieu developed the RootBoard to house the Raspberry Pi Zero 2 W or the older Raspberry Pi Zero (W). The device integrates a 3.5-inch color display and a 70-key keyboard directly into its chassis. A built-in battery enables mobile use without needing an external power source. Integrated speakers allow for direct audio playback from the terminal.
Specifications
- Display: 3.5-inch color display
- Keyboard: 70-key keyboard
- Battery: Built-in battery
- Audio: Integrated speakers
- Compatibility: Raspberry Pi Zero 2 W or Zero (W)
The hardware design prioritizes portability over raw computing power. The system relies on the low-power Raspberry Pi Zero processor for its operations. Users must purchase the Raspberry Pi board separately to complete the setup. The device is currently in active development, meaning final specifications may change before production.
Early backers can secure a unit for around $115 through the Kickstarter campaign. This price excludes the cost of the Raspberry Pi board and shipping fees. Deliveries are scheduled to begin in November 2026. The extended delivery timeline reflects the complexities of producing specialized hardware components.
Handheld PC enthusiasts interested in portable Linux tinkering will find this a relevant option. The trade-off involves accepting a low-power chip and a two-year wait for a specialized terminal. This approach suits hobbyists who value form factor and portability over high performance.
