“Nice little item, makes it a lot neater when using the standard Pi power supply. I can forsee getting more of them for all those other awkward USB C connections.”
“Works as advertised and does indeed carry data. Happens to be the perfect size to fix a major issue with the Argon One case as well, as said case leaves the Pi 4's C port unused in favor of adding a C port of its own that provides power to the GPIO pins instead, thus killing the OTG functionality. With a bit of modification to the HDMI/audio daughter board, IR receiver and case, this adapter can let you access the Pi's own C port.”
