Interface - UARTs (Universal Asynchronous Receiver Transmitter)

A Universal Asynchronous Receiver-Transmitter (UART) is an electronic component that allows for communication between devices using asynchronous serial communication. It converts parallel data from a microprocessor or other device into serial data for transmission over a communication line, and vice versa. UARTs are commonly used in embedded systems and microcontrollers to provide a simple and reliable way of communicating with other devices, such as computers, modems, and printers. They support various protocols like RS232, RS485, and IrDA, and offer features like data buffering, flow control, and error detection.
