Okay as an update,
I've just received the new FTDI Serial interface I validated the serial number to make sure I don't have a fake chip,
I tested the serial interface on a ESP32 project board I have and it's working just fine.
But when I'm trying to use the serial interface with the Rockpro I still only get garbage from the board.
I made sure the interface was in 3.3v mode, and connected the ground to the ground pin of the board (pin 6) and connected the Rx pin of the interface to the Tx pin of the board (pin 8), and left the Rx pin (pin 10) of the board empty.
