Wiring VCNL 4000

I was looking for wiring the VCNL 4000 Proximity Sensor.

I found this one http://bildr.org/2012/11/vcnl4000-arduino/

but there is used a sensor on a red board, which has other pins like mine (which has a blue board) see http://www.adafruit.com/products/466?&main_page=product_info&products_id=466

as I see SCL,DSA,GRND on both

the red has IR+ which is connected to the 5V . mine (blue one) has VIN. Is this meant to be the same and should it be connected to the 5V ?

And furthermore what is the difference between those boards? Are they the same (just newer version?) Any hints?
