PRACTICAL LIMITS: The ATMEGA328 and other chips use about 120mA, so what's LEFT for your LED's, and other external devices is the limitations above minus about 150 mA, so now at VIN of: 7V it's about 550mA, 9V about 200 mA, and 12V 50 mA.

Calculate: I=P/E so available current at 5V = 1.5 / (VIN - 5) (Ref )At 7V VIN this is about 700mA, at 9V VIN it's about 350 mA, at 12V it's about 200 mA.

LIMITATIONS: If an external power supply is connected to VIN, the current available from 5V depends on the power dissipated in the onboard regulator, which is a maximum of about 1.5W.

This can come either from VIN/Power Connctor via an on-board regulator, or be supplied by USB or another regulated 5V supply.

5V.The regulated power supply used to power the microcontroller and other components on the board.

9 volts less than the voltage supplied on the external power connector. Because of the diode, the voltage at Vin will be. The diode is rated at 1 amp and the board traces can't handle much above 2 amp. The current that can be drawn from the Vin pin is limited by the diode and trace width. You can supply a voltage through this pin, or, if supplying voltage via the power connector, access it through this pin. This is connected to the center terminal of the Coaxial 'Power' connector through a 'M7' 1A silicon diode (protection against reverse applied voltage). 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).
