The board can operate on an external power supply of 3.3V to 5V. The recommended
voltage is 5V.
•
The board can be powered via the USB connector or with an external DC power supply.
The power source is selected automatically.
External DC Power supply (non-USB) can be provided from an AC-to-DC adapter (such
•
as a wall-wart) or battery, and can be connected using a 2.1mm center-positive plug
connected to the board's power jack, or directly to the GND and VIN pins.
•
Each of the 14 general purpose I/O pins on the board can be used for digital input or
digital output using pinMode(), digitalWrite(), and
for PWM can be using
source or sink a maximum of 10 mA and has an internal pull-up resistor (disconnected
by default) of 20-60 K ohm.
