I would like to add a servo SG90 to the car so I can open a lid on a container that I am attaching to the car but I am not sure where to plug it in on the board. Can someone assist me? Thanks ---

There is no more interface on the expansion board to connect servos. So it is not possible to add servos to the expansion board. ---

Thank you for the fast response. Is there something that I can unplug to use the servo instead? ---

You can unplug the ultrasonic module or the RGB light bar and connect the servo. They are directly connected to the arduino pins. If you are unplugging the RGB light bar, you have to unplug both to connect to the servo.
