Hi, My beagleboard has arrived and I now have everything in my
possesion to start playing around, except my new power supply is a
regulated 5v multi adapter and i don't know whether the positive
should go to the tip or the negative, embarassing I know. I naturally
don't want to damage my hardware so i was wondering if anyone could
please confirm which way around to plug in the head. Thanks everyone
and please go easy on me.
Rob.
Hi Rob,
Good question, I was just thinking about that myself. I am hoping to power my board up tonight and start playing with it.
The centre pin is +5V according to page 38 of the Hardware Reference Manual: http://www.beagleboard.org/uploads/Beagle_HRM_B4.pdf
I hope this helps

Thats brilliant Geoffrey can't thank you enough, looks like i'll be
able to give a good mess around with the board when i get back in a
few hours, thanks for taking the time to reply (especially so quickly)
and good luck with your own endeavors,
Rob.
No Worries
Good luck

It is center positive, 2.1mm I.D. and 5.5mm O.D… You can find more details on this in the Hardware Reference Manual.
