Orange Pi and Arducam System This section covers how to wire the Orange Pi and Arducam System. This is a vision system that we use as an alternative to the Limelight system.  Background Orange Pi Figure 1 The Orange Pi ( Figure 1 ) is a high-speed single board computer powered by a buck converter which is connected to the PDH. It requires 5 volts to power it this is where the buck converter comes in. Buck Converter Figure 2 The buck converter is shown above in  Figure 2 . Our particular converter is a DC to DC converter which means it transfers the same type of current. What the buck converter does is it turns the 12 volts from the PDH to 5 volts. Arducam Figure 3 The arducam ( Figure 3 ) is a robust high quality camera module specifically created for processors like the Orange Pi and Raspberry Pi. In our system we connect the arducam to the Orange Pi via USB. How to Wire   Figure 4
