Hi,
I have an USB to TTL Serial Cable - Debug / Console Cable #954 from adafruit which i used with RPi devices. Can I use this same cable for Khadas VIM Pro

Cable Info: USB to TTL Serial Cable - Debug / Console Cable #954
There are four wires: red power, black ground, white RX into USB port, and green TX out of the USB port.
The power pin provides the 5V @ 500mA direct from the USB port and the RX/TX pins are 3.3V level for interfacing with the most common 3.3V logic level chipsets.

Hello, I have no knowledge of the specific cable you site. But the 5 volt line will be unused. For me, using a generic serial to USB converter, only RX, TX and GND(ground) are necessary.
See Khadas Docs for more info on this.

Thank you for your replay. I did know that Kadas Docs page but i was unsure regarding this USB TTL Converter and its 3.3V logic level chipset. But it is working fine, here is in case someone have such cable to:

The black lead to GND  Pin17 of VIM's GPIO
The green lead to RXD  Pin18 of VIM's GPIO(Linux_Rx)
The white lead to TXD  Pin19 of VIM's GPIO(Linux_Tx)
