help to connect mma7361 accellerometer to MEGA2560

hi all, I prepared this connection for the accellerometer, please, can you tell me if is correct?

Thank you!

Which MMA7361 board do you have ?
The Arduino Mega 2560 is a 5V board and I assume the sensor is a 3.3V sensor.

Hi, I know just it’s a MMA7361… but I can tell you that the wires schema I posted above is working! And this sensor can handle both 3.3 and 5v!

If you watch the pic I posted you can see 1 pin with 3.3v and another one is 5v so you can choose!

here the result:

I'm not sure that everything is okay. I still would like to know what module with sensor you have.

Ok, here the product info from the shop where I buy this sensor:

MMA7361 Three Axis Accelerometer Sensor Module replace MMA7260

board MMA7361 (replace MMA7260) low cost micro capacitive acceleration sensor

Support 5V/3.3V voltage input, onboard RT9161, pressure drop lower than 1117, faster load the appropriate speed, and is ideal for high-noise power supply environment

range through the microcontroller IO select resistance can also choose

used pin leads pin standard 100mil (2.54mm) convenient for dot matrix board

PCB board sided plated, dimensions: 27.9 (mm) x16.8 (mm)

I have no other info! But I ensure you, it's perfectly working!

So it is a module like these: http://www.banggood.com/MMA7361-Micro-Capacitive-Tilt-Accelerometer-Sensor-Replace-MMA7260-p-84724.html

This is a schematic of the module : http://rfsupplier.com/x2/Steven/Sensors/CGQ-MMA7361-16/GY-32-7361-circuit.jpg

The voltage regulator will make 3.3V for the MMA7361, but I don't know if the control pins allow 5V. I can't read that in the datasheet.

Yeah mate, the sensor is the same! and using 5v I got no problems :) the sensor is currently working good! but if you want you can easly choose to use 3.3v!
