Thanks. I hadn't seen this page.

Unfortunately I won't know this for a while yet, but only having 3A
available at 5V is clearly going to be a problem. The single board
computer alone will probably draw about that much current at 5V, and I
don't know how much the other logic will draw yet.

I want to avoid having either a transformer or a switch-mode power
supply close to the CCB box, so if I do need more power than the
existing supplies can provide, will there be room to mount another
power supply alongside the existing ones?
