> No, but you can wire it for any type of POE you want, whether that be 5v, 12v to 24v, or proper 48v POE. The traces are already there on the PCB, and at that price point I doubt anyone could fit in a buck converter to make it do 48v POE without increasing the cost by a few bucks.
So, you can buy an extra buck converter^ and solder it yourself --removing additional resistors on the PCB-- and it still won't be 802.3af/at compliant, or you can just buy a proper PoE adaptor for $10. [0]
^ Please show me a buck converter that does 48VDC->5VDC for "a few bucks"
> What? You definitely don't need to remove any resistors onboard.
Yes, you do if you're using a voltage higher than 5V. Read the wiki page:
If you plan to use a buck converter at higher voltages, remove R135/R136 (75 Ohm) as they will dissipate a lot of heat and may burn out! See the picture on the right and below in the gallery for which resistors to remove. [0]
