Zero Board POE option

ralbear

Im very interested in the POE option of the zero board, looks like it comes "disabled" by default but i cant find info about how to enable it!

Any news on that?

Any chance we could get some instructions other than what's on that wiki page?  The info is a bit confusing:

By soldering zero ohm resistors passive PoE providing 5V could be used which won't work over large distances since cable resistance is too high

By soldering zero ohm resistors (aka "connecting a wire" or "bridging the gap") to *both* solder pads we can supply 5V via passive PoE injection?  Is that right?

But of course it's also possible to solder a buck converter in between so that passive PoE with the typical voltages (24V or 48V) can be used.

This seems to me like the only "PoE support" provided by the Orange Pi Zero is merely exposed ethernet pins.  If I have to wire up an external buck converter in order to get standard 48V 802.3af working with this board I might as well just use passive injectors and a 2.1mm->MicroUSB connector.

I continue researching around use an standard POE supply, IEEE 802.3af to run this board and this is all i can discover until now.

As @riskable says, yes, to enable de POE in the board is as simple as you can see in the page 10 of the board schema (OrangePi Zero schema) and doing this, you can power the board with 5V POE system

But the problem is to use the POE standard like a POE switch or similar, you allways need to make some external adaptor or similar, one option is the POE board the netduino uses tu work:

I continue with mi research about how to make this boards compatible with an standard POE and come back!

Bulk PCB recycling is essential in managing electronic waste sustainably. Printed Circuit Boards (PCBs) contain valuable metals like gold, silver, and copper, which can be recovered through advanced recycling methods. Proper disposal prevents environmental harm from toxic materials such as lead and mercury. By implementing bulk PCB recycling industries can reduce landfill waste, conserve resources, and promote a circular economy. Investing in efficient recycling solutions ensures a greener future while minimizing the impact of electronic waste on the environment.
