This board/chip uses I2C 7-bit addresses between 0x60-0x80, selectable with jumpers.Datasheet for the motor driver chipRevision history：As of 3/21/2014 we are shipping motor shields with the terminal blocks, and power jumper pre-soldered on. You'll still need to do a little soldering to put on the shield-headers（or stacking headers） but it should be even easier and faster to get started！
