powering Mega with 5 volts

Hey All,

I need to power my Mega board with an external 5 volt power supply: http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=237-1306-ND

What is the best way to bypass the on-board regulator? I've heard talk of going in through the USB jack but I would rather not use a USB cable... Thanks in advance, Francis

The power pins are as follows:

VIN. The input voltage to the Arduino board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin. 5V. The regulated power supply used to power the microcontroller and other components on the board. This can come either from VIN via an on-board regulator, or be supplied by USB or another regulated 5V supply. 3V3. A 3.3 volt supply generated by the on-board FTDI chip. Maximum current draw is 50 mA. GND. Ground pins.

So if it is regulated 5V use the 5V pin.

Yeah just plug it into the 5v and ground pin.

The reason why people use the USB is that it takes advantage of the polarity protection diode. This stops you blowing the board up if you plug the 5v into gnd by accident.
