I just wanted to add that my Digirig Mobile with this cable plus a shielded USB-A to C cable and a Raspberry Pi 3B+ with PiOS and Direwolf 1.7.0 installed on it let me use my Retevis RT95 as my area’s first and only APRS digipeater and igate. Everything worked flawlessly once I blacklisted the snd_bcm2835 sound card driver (which IIRC was for HDMI sound) in /etc/modprobe.d/raspi-blacklist.conf so only the Digirig’s sound card was available. (I think I had to create that file as root too but I don’t remember for sure.) That was my only stumbling block besides learning how to properly configure Direwolf, beacons, and so on.
Now my challenge is to try to get people in Cebu, Philippines interested in using APRS. 
. Anyway, the Digirig’s working flawlessly and will be my go-to digital mode interface unit for any future projects that require one. Thank you!
