![]() The board can be supplied with power either from the DC power jack (7 - 12V), the USB connector (5V), or the VIN pin of the board (7-12V). 5V.This pin outputs a regulated 5V from the regulator on the board.You can supply voltage through this pin, or if supplying voltage via the power jack, access it through this pin. 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).If using more than 12V, the voltage regulator may overheat and damage the board. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may be unstable. The board can operate on an external supply of 6 to 20 volts. Leads from a battery can be inserted in the Gnd and Vin pin headers of the POWER connector. The adapter can be connected by plugging a 2.1mm center-positive plug into the board's power jack. The power source is selected automatically.Įxternal (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The Arduino Due can be powered via the USB connector or with an external power supply. You can find the board without headers at this link. This board is supplied with headers soldered. On the Product itself through our Customer Support.In the Getting Started section, you can find all the information you need to configure your board, use the Arduino Software (IDE), and start to tinker with coding and electronics. You can find your board warranty information here. An unconnected pin, reserved for future use.This enables shield compatibility with a 3.3V board like the Due and AVR-based boards which operate at 5V. IOREF: allows an attached shield with the proper configuration to adapt to the voltage provided by the board. ![]()
