Universal asynchronous receiver-transmitter - Wikipedia
https://en.wikipedia.org/wiki/Universal_asynchronous_receiver-transmitter
A UART is usually implemented in an integrated circuit (IC) and used for serial communications over a computer or peripheral device serial port. One or more UART peripherals are commonly integrated in microcontroller chips.
Basics of UART Communication
https://www.circuitbasics.com/basics-uart-communication/
In UART communication, two UARTs communicate directly with each other. The transmitting UART converts parallel data from a controlling device like a CPU into serial form, transmits it in serial to the receiving UART , which then converts the serial data back into parallel data for the receiving device. Only two wires are needed to transmit data betw...
