Sparkfun MyoWare Muscle sensor

I am a mechanical engineering student and my project is on a myoelectric prosthetic arm, I require the schematic of the Sparkfun MyoWare Muscle Sensor for my thesis report. I have found the various shield of the sensor in the parts library but not the actual sensor.
Could anyone please tell me if the part is present in the library or how to find it elsewhere?
Thank you
