Good Morning, At the source of mimosa says that the RJ 45, 1 and 2 is negative, 3 and 6 positive, which IDENTIFICATION of 8 pin RJ45 wire for mimosa.
Exemple :
pin 1 = negative
pin 2 = negative

The Mimosa PoE provides power on (4) pairs: +VE on 3,4,5,6 and -VE on 1,2,7,8.
However, Mimosa radios have an internal diode bridge that accepts a wide range of inputs.
