Description

DESCRIPTION

The Arduino is very flexible when it comes to power requirements, and is able to operate via the DC Barrel Jack on a supply of 6 to 20V. However, if the board is supplied with less than 7V, the unit’s performance could become unstable, and the 5V I/O pin may end up supplying less than 5V, which could cause additional circuitry to function incorrectly. Vice versa, using an over-voltage power supply up to 20V will cause the regulators on the board to run at full-whack, dissipating the extra voltage as heat. This is both inefficient, and could cause over-heating of the Arduino!

 

Therefore, the recommended voltage is 9V to 12V. This is a nice middle ground which enables the board regulators to easily dissipate any unrequired energy, and additionally supply the correct voltage to the various I/O pins on the Arduino.
