UART on the ESP32

UART (Universal Asynchronous Receiver-Transmitter) is a fundamental serial protocol for point-to-point communication. It’s widely used in ESP32 and Arduino for debugging, communicating with GPS modules, GSM modems, and more.

UART uses two lines: RX and TX. The Arduino’s Serial library and ESP32’s multiple hardware UART ports allow flexible communication with multiple serial devices.
