W5500 PCB layout for POE power input
Account cancelled 2019-06-03 20:48:38 1335 Views1 Replies Hi,
I'm planning on building some products with your awesome W5500 POE board and was wondering if you could share me some more PCB layout details to see if it is possible to tap directly into the 48V that the POE supplies to the board somewhere by soldering onto the transformer for example.
Reading the datasheet it states that the transformer is a 1:1 ratio, so I would think the 48V coming from the POE cable has to be reduced somewhere else before feeding into the circuit?
It would be great to have access to the full power of the POE for some specific applications, so that it would not overcharge the W5500 chip itself.
