TL;DR
The Arduino UNO Q board combines a powerful dual-brain architecture with a microcontroller for high-performance computing and real-time hardware control. It features a Linux environment on the microprocessor unit (MPU) side, allowing users to run familiar open-source software, while the STM32H5 microcontroller operates on Zephyr Real-Time Operating System (RTOS) to manage time-sensitive tasks. This setup opens up a range of possibilities for developers looking to create advanced projects.
