+A **UART** (Universal Asynchronous Receiver-Transmitter) is a [computer hardware](/wiki/Computer_Hardware) device for [serial communication](/wiki/Serial_Communication). It translates data between parallel and serial forms, allowing two devices to exchange information over a single wire pair without a shared clock signal. This simple yet robust method is fundamental to many embedded systems.
