Raspberry PI Board
The Raspberry Pi is a tiny computer motherboard that is the size of a credit card, hence it’s name “card-sized computer.” It is an ARM-based microcomputer motherboard. SD card as the memory hard disk, there are two USB interfaces and a network port card around the motherboard , can be connected to the keyboard, mouse and network cable. There is a video analog signal TV output interface and HDMI high-definition video output interface on it, all the above components are integrated in a motherboard only slightly larger than a credit card, with all the basic functions of the PC, just need to connect the TV and keyboard. It can perform functions such as spreadsheets, word processing, playing games and playing high-definition videos.Raspberry PI board is currently divided into 5 generations with application upgrades.
The First Generation
Raspberry PI Board
This generation of Raspberry Pi board has simple functions and relatively low cost. There are 3 models, Raspberry Pi 1 Model A, Raspberry Pi 1 Model B and Raspberry Pi 1 Model B+.
Raspberry Pi 1 Model A
256 MB RAM, there is only 1 external port and 1 USB port. This was developed for embedded and robotics projects as it limits USB and external ports. It has 26 general purpose Input and Output (GPIO) pins. This model is very lightweight and consumes less power. Nevertheless, the model is still useful in projects where low power and weight are critical, such as high-altitude hot air ballooning and high-altitude flying. Plus, this model with a Wi-Fi adapter is perfect for users who want to use the Raspberry Pi as a media center behind the TV.
Raspberry Pi 1 Model B
1 USB and 100MB of external ports more than Model A, increases 256MB of RAM to 512MB of RAM.Other configurations and functions are the same as those of model A.
Raspberry Pi 1 Model B+
It is the final version of the Raspberry Pi Generation 1, which increases its universal input and output (GPIO) to 40, with the first 26 working in the same way as models A and B. Compared to models A and B, it has 2 USB ports, better hot-plugging and over-current performance. This model also has a Micro SD card insertion interface, a special low noise power supply for audio circuits and a simpler shape with extremely low power consumption.
The Second Generation Raspberry PI Board
The second generation of the Raspberry Pi board only comes in one model, the Raspberry Pi 2 Model B. There are more features and configurations in the Raspberry Pi 2 Model B than the Raspberry Pi 1. It has a BCM 2837 Arm7 quad-core processor that can power single-board computers operating at 900 MHz. This model increases the configuration to 1GB of RAM, which is easily enough to handle more powerful and larger applications. Its geometric area and board layout are almost identical to the of the Raspberry Pi 1 Model B+. It has full HAT (top attached hardware) compatibility. This model’s Universal Input and Output (GPIO)40 pins are fully compatible with Raspberry Pi 1 models A, B and B+.
This model supports cameras with CSI ports. It also has an on-screen display port using a DSI port. It has a Micro SD port for operating system and storing data. In addition, it has a 10/100 external port for quickly connecting this Raspberry PI model to the Internet. It also has 4 USB ports, which provide 1.2 amps of current to any USB port, as it has a very advanced power management system. This Raspberry model can use LibreOffice to create and manage our documents and spreadsheets. We can build our own workstations, time-lapse video, HD audio, GPS tracking, create spatial programming and enjoy faster, more advanced games.

The Third Generation Raspberry PI Board
Raspberry Pi 3 Model B model and Raspberry Pi 2 Model B, both of which have nearly identical hardware ports and features: PCB, 1GB RAM, 4 USB ports, 40 universal input and output ports, a full HDMI port for audio video, external port for audio video. Connect it to any external system, 3.5mm audio and video jack for connection to any external system, DSI port for connecting it to any digital display or LCD display, push-pull Micro SD slot and video core VI for 3D graphics. All of these features are almost identical to Raspberry Pi 2 Model B.
The main differences between Raspberry Pi 3 and Raspberry Pi 2 are: The Raspberry Pi 2 has a quad-core 900 MHz central processing unit (CPU), while the Raspberry Pi 3 has a quad-core 1.2 GHz central processing unit (CPU). It has Wi-Fi and Bluetooth connectivity. The addition of a central processing unit, Wi-Fi and Bluetooth facilities makes it more reliable and compact than other Raspberry Pi models. This advanced Raspberry Pi 3 Model B can be used for advanced applications and projects such as writing our own games, creating wireless expanders, home arcade boxes, TV media centers and more programs.
