Universal Asynchronous Receiver-Transmitter

A UART is a hardware communication interface that converts parallel data from a computer or microcontroller into serial data for transmission, and vice versa for reception. It enables asynchronous serial communication between devices without requiring a shared clock signal, using start and stop bits to frame each data byte. UARTs are commonly used for connecting microcontrollers to computers, GPS modules, Bluetooth devices, and other peripherals in embedded systems. The communication parameters like baud rate, data bits, and parity must be configured identically on both communicating devices.
