The part that the pandaboard.org accessories page links to is this one: "T951-P5P-ND" (5v/4amp)
Digikey still lists that there are about 3332 in stock.
Yes, those are the Panda official supplies which are discontinued due to "an undisclosed issue with their provider which caused them to terminate their relationship with said provider"
I should have mentioned this and thanks to Anand for reminding me... we can continue to purchase those in stock until they are gone. However, there are over 1000 panda boards back-ordered and digi-key is expecting those 3000 to sell out once Panda starts shipping again. I don't see why people would need more than 1 power supply but that's what they are telling me.
