KernelUNO is a lightweight, RAM-based operating system designed for the ATmega328P-powered Arduino Uno. Developed by [Arc1011], it implements a simulated filesystem, an interactive shell, and direct hardware abstraction for pin control. While constrained by the 2KB RAM limit, the OS provides a functional CLI for file management and system commands, modernizing legacy 8-bit development workflows. https://hackaday.com/2026/04/23/kerneluno-an-os-for-the-arduino-uno/
