This is a USB to TTL Serial Cable which allows for a simple way to connect TTL interface devices to USB. The I/O pins of this cable are configured to operate at 3.3V specifically with a Raspberry Pi with each serial pin broken apart. Thanks to its separated pins, this cable is a perfect candidate for powering, connecting, and accessing the login and debug console on the Raspberry Pi.

Hi, I’m looking for USB-TTL 3.3 V adapter cable. This is to connect to my router’s serial port for console debugging. The tutorial I’m following mentions the FTDI TTL-232R-3V3 as an example. Is this USB to TTL Serial Cable ([https://core-electronics.com.au/usb-to-ttl-serial-cable.html](https://core-electronics.com.au/usb-to-ttl-serial-cable.html)) compatible? The connectors look like it’ll be a bit easier for me to connect. I’m running Windows 10… hopefully this cable has necessary drivers?   
  
Thanks!

Hi Carl,

This will work with Windows and is compatible with 3.3V TTL, so it will work. There is no software associated with this product though.
