Universal Asynchronous Receiver/Transmitter (UART)

maker

A UART is a hardware communication protocol essential for asynchronous serial communication.

expanded

A Universal Asynchronous Receiver/Transmitter (UART) is a component used to handle the sending and receiving of serial data between devices. UART functions by converting parallel data from a data bus into serial form and vice versa, facilitating communication without needing synchronization between the transmitter and receiver. It is widely used in applications where simplicity and cost-effectiveness are priorities, such as in microcontroller communications, GPS modules, and Bluetooth modules.

examples

A 115200 baud rate UART interface used in ArduPilot communication.

Commonly used in Unmanned Aerial Vehicles (UAVs) for controlling peripherals like telemetry radios and GPS units.

UART communication in Arduino Uno with default baud rate of 9600 bps for sensor data transmission.

Widely used in hobbyist projects and prototyping to interface with serial-based sensors such as temperature and humidity sensors.
