This is an official and genuine Arduino UNO board, made by authorized manufacturer.
The UNO is an entry level Arduino board and perhaps the most popular board for beginners. It is powered by ATmega328 (SMD) microcontroller. The board has 14 digital I/O pins (6 of them can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connector, a regular DC power jack and a reset button.
How do I power this board?
To power the board, you can connect it to a PC using a USB Type A to Type B cable. This is especially used when you want to upload your Arduino program to the board. Take note that in this mode, current draw is limited to around 500mA only.
Another way to power this board is using the a DC power supply such as wall plug or a battery connected to the DC barrel jack (5.5mm x 2.1mm, center positive). The DC barrel jack for Arduino UNO can accept a wider range of voltage from 7V to 12V. This is our recommended power supply.
How do I program this board?
The Arduino UNO can be programmed using the Arduino IDE.
