xk1

XK1 is a family of low-cost, open-hardware single-board computers designed for education and entry-level robotics. The project emphasizes modular I/O, an open software stack, and affordability to support classroom experimentation and maker projects.

Hardware consists of a multi-core system-on-chip, RAM options from 512 MB to 2 GB, and storage from 4 GB to 32 GB. The base board provides GPIO, ADC, PWM, USB, and camera interfaces, with expansion via standardized mezzanine connectors for sensors, actuators, and wireless radios. A detachable microcontroller subsystem handles real-time tasks and power management.

Software support includes a Linux-based operating system with optional desktop or headless configurations. Development tools cover Python, Scratch, and C/C++. The ecosystem includes a reference image, tutorials, and community plugins under an open-source license.

History: The XK1 project began in 2018 through collaboration among schools and hobbyists seeking an accessible educational platform. Major releases include XK1 v1.0, v1.5, and v2.0, each improving IO options and energy efficiency.

Applications: It is used in classrooms for beginner robotics and electronics, makerspaces for prototyping, and small automation tasks in research settings.

Variants: XK1 Core, XK1 Pro, and sensor-network variants tailored for education and lightweight automation.

Reception: The XK1 is praised for openness and affordability but is noted for modest performance relative to mainstream single-board computers and a smaller developer community.
