The mainboard itself also has two LEDs, one white power LED and one blue user LED. What do they do when you connect your mainboard to a power supply?I made an experience and place a led directly on pins 5V and Gnd but it didn't emitted any light.

If you connect an LED between the 5V and GND pins, you might burn out your LED You need some resistance in your circuit.I made an experience and place a led directly on pins 5V and Gnd but it didn't emitted any light.

You can certainly use the 5V regulated output of a Netduino to power another Netduino. The one thing that I'd watch out for is power consumption (mA) as you mentioned. If you're using networking on both of them, you may start pushing the upper limits powering both from the same source...I have a related question. I have two Netduini + units that will be deployed together side by side. Is it viable to only run 9VDC power to one, then power the second one by connecting the 5V power pin out to the other? Even if this were viable, I would wonder if this risks overheating the voltage regulator of the first unit. Or perhaps it is just best to power through the jack and voltage regulator in all cases?
I'd generally recommend powering each Netduino separately, but this is definitely possible.
