Lear How UART Works

Learn the Basics of #UART Communication

How-It-Works

UART stands for Universal Asynchronous Receiver/Transmitter. It’s not a communication protocol like SPI and I2C, but a physical circuit in a microcontroller, or as a separate IC. A UART’s main purpose is to transmit and receive serial data.

You’ll find UARTs being used in many DIY electronics projects to connect GPS modules, Bluetooth modules, and RFID card reader modules to your Raspberry Pi, Arduino, or other microcontrollers. Learn about URAT on circuitbasics.com
