When using the PoE+ HAT with the raspberry pi 4B, would it be possible to use the USB-C port as a power output, rather than a power input, for instance for an extra fan when the GPIO pins aren't available?

  • Why don't you try it and see? Or even study the published schematics.

  • don't use the RPi as a power supply ... it can easily become an expensive fuse

  • @jsotola then what do you recommend for 2 racks with 2 fans?
