Wiring 3.3V Sensors to 5V Analog Breakout...
Because we somehow managed to fry the KoP accelerometer, we decided to purchase another one (this time analog) from SparkFun electronics - the MMA7260Q (http://www.sparkfun.com/commerce/pro...roducts_id=252 )
We're trying to ensure that we don't short out this one, so we read the directions and other documenation before attempting to wire it to the analog breakout. We Just noticed the analog breakout outputs 5V of current, but the sensor calls for 3.3V...

Will it with with 5V? Did we get the wrong sensor? Is there a way to lessen the voltage?
