The DCcduino Uno was a microcontroller board based on the ATmega328 and compatible with the Arduino Uno -R3. It has 14 digital I/O pins, 6 analog inputs, a 16MHz crystal oscillator, and USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support a microcontroller; simply connect it to a computer with a USB cable and power it with an AC-to-DC adapter battery to get started.
The DCcduino Uno has all the same major connectors as the Arduino Uno R3 or should be compatible with the same Arduino shields. Additionally, there was several extra sets of header connectors – some of which provide extra signals that was not easily accessible on the original board.
All Arduino boards need electric power to function. The power supply is what is used to provide electric power to the boards and typically can be a battery, USB cable, AC adapter, and a regulated power source device.
There are different ways to power your Arduino board. The most common way was through the USB connector available on every board, but there are a few other possibilities to power your board. If you like to know more then about this, the different ways to supply power to your board are listed below.
Arduino boards can operate satisfactorily on the power that is available from the USB port. It provides 5V DC voltage and they can be sourced from the port from a PC, wall socket adapter, and portable power bank.
Some Arduino boards like UNO, MEGA, and DUE, come with an AC socket that could be used to power the boards and to supply additional voltage if needed. A power supply adapter that provides from 7 to 12V (Volts) of DC (Direct Current) was required. The adapter was plugged into the wall socket and the other end goes directly into the board’s AC socket.
Another way to power your board was by supplying voltage from the regulated power source directly to the VIN pin. Just need to connect the positive wire from your power supply to the VIN and the negative to the GND. Follow your board power specifications to figure out the voltage range that your board could handle. VIN pin is an INPUT only.

The USB port serves two purposes: First, it is the cable connection to the computer which allows you to program the board. The USB cord would also provide power for the Arduino if you're not using the power of the port (described below).
The Arduino Due has two USB ports available. The Native USB port (which supports CDC serial communication using the SerialUSB object) is connected directly to the SAM3X MCU. The other USB port is the Programming port. It was connected to an ATMEL 16U2 which acts as a USB-to-Serial converter.
Arduino USB Type-C® Cable 2-in1 Now you can connect your Arduino boards to the official Arduino USB Cable. Through the USB-C® to USB-C with a USB-A adapter connection, this data USB cable can easily connect your Arduino boards ...
Mostly, USB cables are connected to the computer units directly to peripheral devices like mobile phones, cameras, camcorders, or printers/scanners. The main objective of these cables is to effectively, quickly, and properly gather or transfer data from one device to another.
If you were to open up a USB cable, you would notice 4 different USB wire colors: white and green, which carry data, and red and black, which are used for power. Red carries 5 volts or acts as the positive wire, while black has the negative wire, otherwise known as the ground wire.
