This is a very simple RJ45 PoEthernet MagJack connector that can help connect you to the Internet with the ability to provide power. Power over Ethernet, or PoE for short, is a system that’s designed to pass data and power, safely, over the same CAT5 cable. This specific connector was once used for our (now retired) [SparkFun PoEthernet Shield](https://www.sparkfun.com/products/retired/10864). We found out we still had some left over stock and wanted to give you the opportunity to capitalize on the low price.
Inside each RJ45 are a number of transformers and magnetics required for isolating Ethernet signals. There are even some LEDs poking out the end.
**Note:** We are currently waiting on our supplier to get a Datasheet for the RJ45 PoEthernet MagJack. Check back soon for more information.
