Re: Does the PD board Output 12v Stable?

Assuming I'm correct with my understanding, the answer to the original poster's question is that for the 12V supplies that you're allowed to use for custom circuits, the answer is no, they are unregulated and therefore will not work for anything that is picky about 12V.
You are correct, that supply may only be used for the gaming adaptor.

The rest of the outputs are unregulated.

The 5V supply will only ever output 5V or 0V. If it can not provide a steady 5V, it gives up.
