[How to make the POE work]
[About the POE Adapter]
As the max. input of the fan & power board is 14V, so please be careful, the POE adapter must be the one with the voltage step-down function to make sure the output power of the adapter to be 12V for our fan& power board.
In general, ethenet power input voltage usually is 48V or 32V or 24V or other ...
There is NO voltage step down function for our POE adapter because we don't know you use what ethenet power voltage.
There are several kind POE adapter such as:
48V step down to 12V
32V step donw to 12V
24V step down to 12V
Please DON'T use our POE adapter if your ethenet power voltage is more than 12V, or the Fan&Power Hat will be damaged;
If you need the other POE adapter, plese buy it online;
