⚫
For USB 3.1, it is suggested to do simulation after the design is completed. If the cable is too long or
there are too many vias, a redriver needs to be added to ensure the quality of signal transmission if
necessary.

3.10. UART Interfaces
The module provides three UART interfaces:
⚫
UART0: four-wire UART interface, supports RTS and CTS hardware flow control
⚫
UART4 (debug UART): two-wire UART interface, used for debugging by default
⚫
UART1: two-wire UART interface
