Which cable to use for 40 PIN GPIO connector

A standard 40 PIN GPIO cable is too wide and the center foot also does not fit

Hi, who is the vendor of the cable? You should check with vendor for this.

It is a standard cable. Maybe there is a special cable for the Xavier that does not require to connect each pin separately.

It should be just a standard double row of 20 pins, 0.1" spacing. However, there are such connectors with and without keying…the keying does not exist, so you’d need just a generic 0.1" spacing without keys or guides (basically, grind off the center key).
