1. Serial Port Debugging

1.1 Wiring Instructions

EASY EAI Nano-TB supports debugging via the debug serial port. The relevant hardware interface is shown in the figure below.

After the serial port is correctly recognized by Windows, you can check the specific serial port number (e.g., COM7) through Device Manager, as shown below.
