Note that you can run the DMD directly from the EtherTen board if you don't need to run at full brightness - and as shown in the video above it's fine for indoor use. Using the midspan injector saves having to have a power supply for the hardware at the point of installation, so the only cable required is the Ethernet run. This is a great example of Arduino, power-over-Ethernet and using our equipment. For more informaiton, visit this Envato page.
