This is a breakout board for Freescale's triple-axis MMA7260QT accelerometer. With a low power shut-down mode, high sensitivity output with selectable ranges (±1.5, 2, 4, and 6g), this was one of the very first sensors to market with three accelerometers built onto a single IC! Board comes fully assembled and tested with external filters installed.
The MMA7260QT is a 3.3V part and outputs an analog voltage for each of the three outputs. This voltage is in ratio to the measured acceleration and to the supply voltage (ratiometric). You will need some extra hardware to convert this analog signal to a usable digital one. Luckily, many uCs have a built in Analog to Digital converter.
