motor shield pins not matching arduino uno inputs

2 pins on the right and left side not going to an input and i got the motor shield from radio shack

Every part I've ever bought from Radio Shack came in a package with a part number on it. Did yours? Do you have a link to the part?

Does it look like the one in the picture? That looks to me like one side is correct, at least.

nvm the 2 pins are for the arduino mega

thanks!

The Uno R3 has extra pins:

The Uno R3 also adds SDA and SCL pins next to the AREF. In addition, there are two new pins placed near the RESET pin. One is the IOREF that allow the shields to adapt to the voltage provided from the board. The other is a not connected and is reserved for future purposes. The Uno R3 works with all existing shields but can adapt to new shields which use these additional pins.

Add: The Mega2560 R3 also has the extra pins. These are the models sold by Radio Shack, so the shields they carry will probably be designed for them.
