I have a number of RPi 4 boards that I'm clustering together in a single case.
To consolidate power to a single wall outlet, I have them all connected together via a dedicated switch with PoE at each port. At 15w under load, the power over ethernet supplied is more than enough for each node.
The problem is, the PoE HAT I'm using requires use of all 40 GPIO header pins.
I'll have no pins left on any of the nodes to power other devices, namely the case fans.
Is there a dummy device out there (in the same form factor as the Pi) that could power 4 50mmx50mm fans?
