How much current can be drawn from Arduino?

There are 16 digital pins on the Arduino board. They can be used as inputs or outputs. They operate at 5V and have a maximum current draw of 40mA.

How many amps can Arduino input?

By specification the adapter output is 2.5A allegendly on all modes.

What are the current limitations in mA for the Arduino Mega board?

The Arduino Mega has in total one 3.3V pin and four 5V pins, which are able to provide a current up to 50 mA.

What is the maximum operating voltage of the Arduino What is the maximum current draw on each output pin?

Warning: Unlike most Arduino boards, the Arduino Due board runs at 3.3V. The maximum voltage that the I/O pins can tolerate is 3.3V. Applying voltages higher than 3.3V to any I/O pin could damage the board.

How much current does an Arduino Nano draw?

How many watts can an Arduino take?

The Arduino Uno board draws about 42 mA assuming no power draw from sensors or other components needed in your system. With a minimum supply voltage of 7 volts, the power consumption of the board is therefore 0.29 Watts.

How much voltage can Arduino Mega handle?

The board can operate on an external supply of 6 to 20 volts. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may be unstable. If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 12 volts.
