4.1 Application – UART

A common use case for UART interfaces is as a communication link between devices.

An example is the communication between the circuits of a wireless speaker. The 2N7001T provides a simple solution for voltage level shifting between the processor and MCU. Figure 4-2 shows how an UART interface could be used for enabling the communication between the processor and the Wi-Fi block.
