UART

With TTL-UART make troubleshoot uncomplicated!

SoC Total Pin RX Pin TX Pin
RTL9601CI 76 13 12
RTL9601D 88 16 15

For GND and VCC (3.3) you need SFP Breakout Board to power it via external source, TTL-UART (CP210x) not enough power!

If you unable to get SFP Breakout Board, you can get SFP Seat (without cage) and power that way.

To avoid solder XPON Stick, use Flying Probe to connect tiny pin into tiny pad.
