UART
makerA UART, or Universal Asynchronous Receiver-Transmitter, is a hardware communication protocol used for asynchronous serial communication.
expanded
UART is a key component in microcontroller systems for enabling data transmission over serial ports without needing a clock signal. It translates the data between parallel and serial forms, facilitating communication between the microcontroller and peripherals such as sensors and actuators. Its practicality is evident in low-cost, low-speed communication tasks in embedded systems, like remote sensor data acquisition.
examples
The ATmega328P microcontroller uses a UART interface to communicate with GPS modules, facilitating real-time location data transmissions.
Commonly used in Arduino-based projects, such as DIY GPS tracking systems.
A Raspberry Pi 4 utilizes UART for debugging purposes, enabling console output and diagnostics without a direct monitor connection.
Typically employed in headless configurations where the Raspberry Pi operates without a direct display.
