UARTUART, or universal asynchronous receiver/transmitter, is a type of integrated circuit that is used to interface with serial communication devices. UARTs are commonly used in devices that need to communicate with other devices using a serial communication protocol, such as RS232 or RS485. A UART provides the interface between the device and the serial communication line, allowing the device to transmit and receive data using the protocol. UARTs are typically used in a wide range of applications, including consumer electronics, industrial automation, and telecommunications. They are available in a variety of form factors, including standalone chips, modules, and integrated circuits that are embedded on a motherboard or other circuit board.
