Alternative to the PDP and VRM

[Kevin Sevcik]

Note that if you're using CAN for anything (other than your non-existent PDP) you'll need a 120ohm termination resistor at the end of your chain to stand in for the missing PDP.

I assume you are also using the old radio and you need (or already have) a source of 5V and ~2A.

If you ask around teams in your area, someone will probably loan/give you a 12V to 5V converter that used to be required for the radio, due original radio being 12V. It looks like this one (common style):

AndyMark and others sell this one:

ServoCity has this Step up/Step down one:

I haven't used either of the last 2 products, but I probably am going to buy the last one (if I can't find a similar higher amp one) to power some cameras rather than a 2nd VRM. Of course, you could always make your own circuit with parts you might already have.

There are cheap PDB for the cRIO on eBay right now.
