 == Hardware ==
 Hardware boards (depending on the manufactured model) contain interfaces:  Ethernet, Bluetooth, WiFi, USB, AUDIO, HDMI and GPIO ports ((https://www.raspberrypi.org/documentation/hardware/raspberrypi/README.md)). The Raspberry Pi boards have evolved through several versions varying in memory capacity, System on Chips (SoC) and processor units. The first generation models of Raspberry Pi used the Broadcom BCM2835 (ARMv6 architecture) based on a 700 MHz ARM11176JZF-S processor and VideoCore IV graphics processing Unit (GPU). Models Pi 1 and B+, developed later, use the five-point USB/Ethernet hub chip, while the Pi 1 Model B only contains two. The Pi Zero USB port is connected directly to the SoC and uses the (OTG) micro USB port.

+===== Raspberry Pi Boards =====
 As for today, on the market, a few models of Raspberry Pi boards are available, from tiny ones to more powerful ones. Users can choose the right board to fit the price and functionality of their project development needs. Figures {{ref>rpi1}}, {{ref>rpi2}}, {{ref>rpi3}}, {{ref>rpi4}}, {{ref>rpi5}}, {{ref>rpi6}}, {{ref>rpi7}}, {{ref>rpi8}}, {{ref>rpi9}} and {{ref>rpi10}}, are presenting Raspberry Pi models, starting from the simplest and finishing on the most advanced and most modern ones.

+===== General-Purpose Input-Output (GPIO) Connector =====
 Each Raspberry Pi model is equipped with a standard 34/40-pis male connector containing universal GPIO ports, VCC 3.3/5V, GND, CLK, I2C/SPI bus pins, which developers can use to connect their external sensors, switches and other controlled devices to the Raspberry Pi board and then program their behaviour within the code loaded to the board.
   * Raspberry Pi 1 Models A+ and B+, Pi 2 Model B, Pi 3 Model B and Pi Zero (and Zero W) GPIO J8 have a 40-pin pinout. Raspberry Pi 1 Models A and B have only the first 26 pins.

-==== Display Port (DSI) ====
+===== Display Port (DSI) =====
 Raspberry Pi boards 2 to 5 have an LCD Display interface(DSI) port, allowing the user to connect the LCD touch display to the board.
 The official Raspberry Pi LCD touch display shown in the figure below is 800 x 480 dpi 7" in size and can be connected to the Raspberry board using the DSI interface. Such an assembly can be used in the projects to display a controlling application view, and the ability to handle fingers and a touchscreen controls the project behaviour. The LCD can be mounted in portrait/landscape orientation, fitting the best user needs.

+=====USB and LAN Ports=====
 Raspberry PI models Zero, 1, A+, 2, 3, 4 and 5 contain USB ports (from 1 up to 4), and all but Zero also have a LAN port for TCP/IP network connections. These ports can be used for mouse/keyboard connection or if the software has the appropriate driver installed to handle other USB devices.
