I'm just starting a project with the above mentioned hardware (Arduino Uno With PoE Ethernet Shield). Both are Arduino and Say R3 on them.
I haven't hooked up the hardware yet because I don't have a PoE injector for it yet.
I am going to buy an injector. My question is can I buy one with adjustable output voltage, just in case the 24VDC (which most are) is too high a voltage and causes my shield to run hot?
If you know of any the manufacturer's name and part number would be appreciated.
Standard PoE injector/switch (IEEE802.3af/at) can recognize the power of your Powered devices needed automatically. You can use PoE splitter if your devices not built in PoE module. www.mebary.com
