Power Supply Module

For many of the devices used on the IGVC robot, the 24V supplied by the batteries is too great. Therefore, a power supply module sits between the 24V fuse block and several devices. The module provides power to the IGVC Laptop and the JVC Camera specificly. Also, 12V runs out of the supply to a 12V fuse block, providing power for devices such as the Joystick and Sonar.
