power adapter question

Can I use the same BB-XM Power supply for the BBBlack?

Yes. They have the same connectors. They have the same polarity. And they are both 5Vr. Now, as there is no official XM power supply, you need to make sure the one you bought has the right amount of current for you application.

Yes it is center positive. I used the same power connector on all four designs.
