LPC824 from external power source

I am trying to power the LPC824 Xpresso v2 board using an external power supply instead of powering from USB.  I can use USB for power while programming, but then I want to be able to run it without the USB plugged in after it is programmed.

 

It is not clear where and how much voltage I supply.  I tried 5V to the Vin pin but that did not work.  The built in LED came on, but no firmware was running.  When I disconnected this and provided power via USB it works fine again.
