USB Serial
USB Serial is a communication protocol and driver system that enables serial communication over USB connections, allowing devices like microcontrollers, sensors, and embedded systems to interface with computers as virtual COM ports. It converts USB data packets into serial data streams, facilitating debugging, programming, and data exchange in hardware development. This technology is widely used in electronics, IoT, and robotics for connecting peripherals that traditionally used RS-232 serial ports.
Developers should learn USB Serial when working with embedded systems, Arduino projects, or IoT devices that require communication with a PC for configuration, logging, or control. It's essential for debugging hardware via serial monitors, flashing firmware to microcontrollers, and building applications that interact with sensors or actuators over USB. Use cases include prototyping with development boards, industrial automation, and creating custom USB-based tools.
