TL;DR
The article discusses the Arduino VENTUNO Q board, which integrates a Linux-capable Microprocessor Unit (MPU) and a real-time Microcontroller Unit (MCU) on a single board, designed to simplify communication between the two in robotic applications using ROS 2 (Robot Operating System). This dual-brain architecture eliminates the need for complex serial protocols or middleware when connecting the high-level functions of the Linux side with the deterministic tasks handled by the microcontroller.
