UART stands for Universal Asynchronous Receiver/Transmitter

UART stands for Universal Asynchronous Receiver/Transmitter, and it is a form of serial communication used for short distance communication. It is a very common communication protocol used in embedded systems, and is often used for communication between devices such as sensors and microcontrollers. UART module  is a full-duplex protocol, meaning that data can be sent and received simultaneously.

UART is a relatively simple protocol, and it consists of a data line, a clock line and a control line. The data line is used to transmit and receive data, while the clock line is used to synchronize the data. The control line is used to specify the direction of data flow, either from the transmitter to the receiver, or from the receiver to the transmitter.

UART is an asynchronous protocol, meaning that data does not need to be sent and received at the same rate. This allows the system to be more flexible, as the receiver can receive data at different speeds depending on the type of data being sent. Additionally, UART is relatively inexpensive and easy to implement, Wireless modem making it a popular choice for embedded systems.

UART is a popular choice for communication between microcontrollers and other devices, such as sensors. UART is commonly used in medical devices, industrial automation systems and robots, as well as in some consumer electronics. UART is also used for communication between computers and peripherals, such as keyboards and mice.

UART is a reliable and robust protocol, and it is widely used in embedded systems. It is an effective protocol for communication between devices, and it is relatively inexpensive and easy to implement. UART is a great choice for embedded systems that require short distance communication between devices.
