In-Depth Information
On the back of the module, the connections are labeled as follows:
The following are the connections that you'll need to make between Arduino and the
device:
Arduino pin
Sensor pin
5V
5V
GND
GND
A5
SCL
A4
SDA
Notice that you will not connect the 3.3V or DRDY (data ready) lines. Our Arduino sup-
plies power through the 5V line instead of the 3.3V line, and the DRDY line is not needed
by this library. Now, you are ready to talk with the device using the IDE.
