There are only four pins that you need to worry about on the HC-SR04: VCC (Power), Trig (Trigger), Echo (Receive), and GND (Ground). This is directly compatible with the Robot Core v1.2. There are 4 open ports for these sensor types. Robot core has built-in examples/libraries to make interfacing with this sensor easy.  Tired of buying cheap knockoffs? These sensors are built stronger and are not as flimsy. They are also lead free.
