      MMA7331L 3-axis ±4g / ±12g Accelerometer with Volt.Reg (MR003-003.1)

      This carrier board has been developed for the Freescale MMA7331L XYZ-axis accelerometer, a great low-g sensor with analog voltage outputs and adjustable sensitivity (±4g or ±12g), and it includes all the external components required by the sensor.
      Its very small size (25.4x12.7mm) and its very light weight (only 1.1g), make it the perfect peripheral for small robots and for motion sensing systems.

      The MMA7331L is a low power, low profile capacitive micromachined accelerometer featuring signal conditioning, a 1-pole low pass filter, temperature compensation, self test, and g-Select which allows for the selection between 2 different sensitivities.
      Sensitivity is factory set and requires no external devices. The MMA7331L includes a Sleep Mode that makes it ideal for handheld battery powered electronics.

      Another great feature of this product is the presence on-board of a 3.3V 50mA very low dropout linear voltage regulator, which allows this breakout board to accept a wide range of input voltages (2.7-6V).
      Due to the low power consuption of the MMA7331L sensor a lot of power can be used for additional 3.3V components.
      Note that for power saving sensitive applications it is possible to shut down the sensor, reducing the current to less then 3uA.

      This board breaks out all the signals to a 0.1” (2,54mm) standard spacing header, in this way it is simple to use it with prototyping boards and also with breadboards.

      Typical applications are:

      • 3D gaming
      • motion sensing
      • robotics
      • navigation.

      For more details about the sensor please refer to the Freescale MMA7331L datasheet.
