2. I'm not entirely sure if this would work, but I think you could use the router power supply from last year plugged directly into a wago on the PDP. That supply is a 12v-5v supply, but the camera requires a very specific voltage and I don't know how good the regulator is in the router power supply.
edit: I looked up the spec sheet for that, says it works from 10-30v, which doesn't sound too promising. I know our batteries get down below 10 during some matches.
Perhaps you could put that thing off the 12V2A rail of the VRM, although I'd advise against it, especially if you're using pneumatics with your compressor PCM plugged into the weidmuller connectors, because your compressor, solenoids, and anything off the VRM will run off a single 20A non-resetting fuse.

The VRM was designed specifically for FIRST use. Teams need 5V and 12V.
Having boosted 5V and 12V is great because of the different radios teams have collected over the years. And they are boosted to tolerate battery voltage drops.
The radio selection changes year-to-year, the VRM allows us to be flexible and support the widest combo of peripherals. Seems like a good design practice to me.
R37 tells us additional (non-radio) VRMs can be connected to the WAGO slots on the PDP. So you don't have to rely on the 20amp fused weidmuller if that's a concern. Seems like a good solution for camera.
