Description
Description
Read the full guide on diy through-hole poe+ splitter.
This post is part of a series on PoE (power-over-ethernet), see the first two posts here:
In this guide, we are taking the concept one step further by using "smart" PoE, by using the 802.3at standard to negotiate the level of power we want from the PoE switch. Read more about 802.3at specification here.
