You can connect 5V power into the USB connector, or into the gnd & 5V pins.

To follow up on what Paul said...yes, you can power your Netduino Mini from a 5V power supply as long as it's a regulated power supply. Just use the 5V and GND pins on the right side and you should be good to go.I'm affraid it is not possible, but...: Can I power a netduino mini from a 5V power supply, directly? (Without using additional components like a DC-DC converter)

I've been powering my Mini for some time with an old 5V Motorola cell phone charger through the Vin pin with no problems. It may be more correct to use the 5V pin though... It took me a while to learn that it was both an input and an output.PS, those old cell phone chargers work great, and I've accumulated dozens of them over the years :-)
It would be better to use the 5V pin or USB input. There is a regulator between the Vin pin and the 5V rail; even though the input is already 5V this regulator will result in a small voltage drop.
I have a stash of old phone chargers waiting for service in new gadgets, but they never seem to be the right voltage when a need arises!
Be careful when using recycled chargers, they are built as cheap as possible and probably only just meet the ratings written on them. You may find that as your project takes more current, the voltage drops or it becomes unstable / has a ripple on it.
