Do you have the CRIO and similar connector outputs unplugged or disconnected from the PD board? I still think you still need to completely eliminate the possibility of a short on something you are driving. A short elsewhere may make it look like you have a bad PD board when the problem is actually in the wiring. Also, are you completely sure that you have the positive voltage going to the correct lug of the PD board? Check that with a meter as well. Even a battery could have been accidentally wired so that + voltage goes to the wrong terminal. The students are often quite eager to put things together and do not always realize that the polarity matters here.
When I have a problem with something like this I start by not trusting anything and recheck the simplest things.
