Stacking Shields
If you want to plug shields on top of this one, make sure you pick up a set of shield-stacking headers
http://www.adafruit.com/product/85
and solder them instead of the male header
Since this shield only uses the I2C pins and the I2C bus is sharable, you can stack multiple shields on top of each
other. You will need to have installed stacking headers & right angle 3x4 connections for it to physically connect.
Multiple shields (up to 62!) can be stacked to control still more servos.
You may have difficulty with the 'left-most' header since we updated the transistor to be beefier. Use the 3 ports to the
right or solder wires out to get mechanical access
