Arduino Mega 2560 REV3

I have been using an older version of arduino and so I just picked up a brand new rev 3 and rev 3 motor shield from radioshack. First issue is it does not have all of the pins it shows in the picture. The box shows an 8 pin header where the 5v 3.3v and 2 gnd pins are. The motor shield has 8 pins which is correct but the actual arduino only has 6 pins. What should I do?

I would take the mega back to Radio Shack - it's not a rev 3 board if it's missing the two pins. I won't voice my opinion as to how the wrong board ended up the box...

Thats what I figured. Well im definitely going to take it back. I guess I will order one.

I took the board back to radioshack. They opened up another box and it had the real rev 3 in it. They swapped the board with the one i purchased yesterday. Crazy thing is I watched the lady put the old box with the wrong chip right back up on the shelf. Pathetic...

Glad that you got your rev 3 board. I prefer mail order myself from reputable, established Arduino dealers. I have also succumbed to the desire to "have it in my hands now" that keeps RadioShack in business though.

Sounds like a plausible explaination to how you ended up with a different rev (or clone). Someone else "returned" it.

Some people take pride in their jobs. Some people take pride in the fact that they don't.
