In-Depth Information
The interface to the board is quite simple, with only one issue. One of the ways to connect
this particular chip is to solder header pins to the board to connect the jumper wires to Ar-
duino. You can purchase these at
sparkfun.com
as well; just search for the Arduino stack-
able header, 8-pin version. Once the header is soldered, the device will look as follows:
Now, you can use a male-to-male jumper cable to connect between Arduino and the
board. The following table shows the connections:
Arduino pin
Sensor pin
3.3V
VDD
GND
GND
A5
SCL
A4
SDA
3.3V
VIO
You'll notice that you need to make two connections to the 3.3V supply, so you may want
to create a male-to-male jumper cable with two connections on one end. This can be done
using three male-to-male cables. For this, we need to cut off one end and strip back the in-
sulation, then solder the three cables together, and then wrap the solder connection in elec-
trical tape.
