Is possible to use R5H on RB14? I can see RB14 can supply upt to 2.5w per minipci, and even an R52 can eat up to 2.64w max. Surely is 2.5w/minipci or is 5w/2xminipci, I can see there are two stabilizers on the adapter. R52H is rated at 600mA typ., R5H does not have power req. in the specs.
Later I’ve found on the forum
310mA@3,3V RX only
1,6A@3,3V RX and TX at full power
so it means that R52H specs are wrong…
The question remains: is the power 5W splited between 2 minipci ports?
I will answer myself 
"You cannot use regular RB14 with 4 SR wireless cards, however you can use two SR wireless cards, plug them to the one side of the RB14, either RB14 might be damaged. " - so 5w is splited
I’ve also found:
“sergejs - Current RB14 is able to handle 4 high power wireless cards (R52H).”
If R52H has 350mW and R5H have the same power, why Normis said that it needs 1.6A?
