+**Comparing Simulated and Real Motor PWM Signals**
+With the addtion of the Zybo PCB shield, MicroCART users can now compare motor PWM signals measured from test points on the PCB shield with simulated motor PWM signals created by the Simulink simulator. This is useful for verifying that a controller is behaving as expected without needing to risk damaging the quad during test flights.
