1.1 USART

The Universal Synchronous/Asynchronous Receiver/Transmitter (USART) is an integral communication module embedded within microcontrollers to facilitate serial data exchange. This versatile component can manage both synchronous and asynchronous serial protocols, transmitting data sequentially, bit by bit.

USARTs offer a high degree of configurability, allowing for an array of data frame structures, baud rates, and modes of operation. It is a full-duplex in operation. This adaptability renders them highly suitable for interfacing with various devices, including sensors, computers, and additional microcontrollers.
