Where to find serial cables

MOX hardware MOX HW help

Hi!

I was able to find a 3.3V serial cable at Adafruit which i believe to be compatible with my Turris Omnia, which I needed here:

… but I can’t find the 1.8V cables that are supposedly required, according to the serial port documentation.

Where can I find such a cable?

thanks!

The omnia cable with a simple voltage divider on the RX side of the MOX will do the job,
If you care to tinker with resistors.

Something like this

Or you can buy this but read the specs as I think you need to supply the appropriate voltage.
There should be 1.8v out on the gpio header on the MOX, check the mox gpio link

Awesome! I already gave up searching for a 5/3.3/1.8 cable, but this one seems to do the trick.

Anyways, the “canonical” or “safe” option for 1.8 V cable is FTDI TTL-232RG-VREG1V8-WE. It’s not cheap, but it’s guaranteed to do what it says.
