Allows me to run my pis in my rack with only one cable for network and power. It’s how I run all my SoCs, I hate cable management, so I reduce cables as much as possible.
As someone who is (somewhat) interested in doing a similar setup like yours – does it stack? As in, energy is divided between all pis that are connected to that single cable?
Not quite. You need to run a cable from a PoE(power over Ethernet) port on a capable switch to each pie. You just need power to the switch and the switch will power all the pis through their own individual cable. You are only limited to the power supply on the switch you use.
thousand reasons to use Poe for tiny devices like this. Ethernet is easier to run for cameras, security setups. don’t need a plug if you’ve got a switch on your workbench. one less cable to run.
