The EnderIO mod combines many different features into a single mod which doesn’t seem to have any particular focus. There are several interactions with Redstone circuitry, so you could probably call it a Redstone mod if you had to call it anything. A recent update removed BuildCraft from Ender IO, along with all of the MJ usage which went with BuildCraft. Now, this is a total Redstone Flux mod, so if you want to use Ender IO, it would be a good idea first to become more familiar with Redstone Flux and how it works.
Ender IO is valid for players who want to craft computers in Minecraft because of the wide range of circuits it allows the user to create. ME Conduit, included with this mod, features courses that support eight different channels and will enable you to do much more than you’re used to with the same amount of resources you’re accustomed to using. In this sense, Ender IO is also a great mod for players looking to conserve resources and get the most out of every bit of Redstone dust they find while mining and adventuring. You have to check it out for yourself to understand it.
