Is UART Different from USART on the Arduino Uno?
Funny enough, the atmega328p which is the chip on the UNO makes mention of the USART not UART in its documentation. This module is capable of both synchronous and asynchronous serial communication. When you we use the Serial object in your Arduino code, you’re leveraging the asynchronous mode of the USART, effectively using it as a UART. The Arduino platform actually abstracts away the complexity, so most users think of it as UART. I think the synchronous feature is generally not used in standard Arduino sketches, which is why most references in the Arduino community refer to it as UART.
