WINGONEER Green Light Optical Fingerprint Reader Sensor Module for Arduino Mega2560 UNO R3

The sensor works for what it is, but the photos in the description are not the actual item. I received a JM-101B, but I was expecting the same model sold by Adafruit since that is what is pictured in the description. The two most obvious differences are that the light on this product is actually blue, and the Tx pin on my model is yellow and Rx is white. Photos in description do not apply at all to this product. Buyer beware, you will have to do some research to get this to work with Adafruit Fingerprint library.

Came in on time, but it is not the product I ordered. The module in the picture and description is not the same as what I got. The pins and diagrams don't even align. Very disappointed.
