MMA7361 (MMA7260) ACCELEROMETER

This is a breakout board for Freescale’s MMA7361L three-axis analog accelerometer. The MMA7361 Accelerometer Module is a triple axis micro capacitive acceleration sensor. It features an easy analog programming interface where each axis reports acceleration as a voltage level. The sensor requires a very low amount of power and has a g-select input which switches the accelerometer between ±1.5g and ±6g measurement ranges. Other features include a sleep mode, signal conditioning, a 1-pole low pass filter, temperature compensation, self test, and 0g-detect which detects linear freefall. Zero-g offset and sensitivity are factory set and require no external devices.

Specification:
Two selectable measuring ranges (±1.5g, ±6g)
Low current consumption: 400 µASleep mode: 3 µA
Low voltage operation: 2.2 V – 3.6 V
High sensitivity (800 mV/g at 1.5g)
Fast turn on time (0.5 ms enable response time)
Support 5V/3.3V voltage input, onboard RT9161, lower pressure drop than the 1117, faster load the appropriate speed, is ideal for high noise power supply environment.
Dormancy so that energy can be controlled through the microcontroller IO.
Dimensions: 28 * 17mm

Note that only one of the two power supply inputs (either 5V or 3V3) should be connected and that the sleep mode input must be set to a logic high level (3V3) to operate normally. Also as the MMA7361 works in 3V3 mode, you should set the analog reference voltage of your Arduino to 3V3.
