MMA8652FC daughterboard pin out

[øysteinkristian]

Hi, I want to use MMA8652FC daughtboard found in FREESCALE sensor kit http://www.freescale.com/products/sensors/accelerometers/3-axis-accelerometers/sensor-toolbox-boards... with my ARDUINO UNO board, but I don't know the pin out. Can someone help with this?

Hi Øystein,

Attached you can find the schematic of the MMA8652FC accelerometer daughter board.

There are four pins that need to be hooked up in order to start using this sensor.

MMA8652FC board -> Arduino

VDD (J1-1 or J2-3) -> 3.3V

GND (J2-4 or J2-5 or J2-7 or J1-5) -> GND

SCL (J1-4) -> A5 (or SCL)

SDA (J1-6) -> A4 (or SDA)

If you are using a 5V Arduino Uno, I recommend putting 330 ohm resistors in line to limit the 5V signal going into the MMA8652FC and prevent damage to the sensor.

I hope it helps.

Regards,

Tomas
