Raspberry Pi, developed by the Raspberry Pi Foundation and first released in 2012, has become one of the most popular platforms for developers. This low-cost computer connects to a monitor and can function as a regular computer by adding a mouse and keyboard. In the Raspberry Pi Tutorial Part 1, we will delve deeper into the history of Pi and its capabilities.
You can use this little Raspberry Pi board to do what your computer can do. Web browsing, video playback and high definition games are now available on the Pi. You can learn programming languages and explore the world of information technology. The original idea behind this tiny computer was to teach the basics of programming to children.
Different versions of Raspberry Pi
Raspberry Ρi 1
The initial line of Raspberry Pi started with the Raspberry Pi 1 Model A released in February 2012. Followed by this, the Raspberry Pi 1 Model A + was the successor to the Model A released in November 2014.
The A series had basic specifications at a very affordable price, but for those who demanded more, the Pi 1 B and B + were other revisions of the Pi 1 with more powerful specifications. The first-generation model of the Raspberry Pi provided the same graphics capabilities as the 2001 Xbox.
RPI 1 Model B + Specifications:
- 512 MB of RAM
- Four USB 2.0 ports
- Ethernet port
- Full size HDMI output
- 700 MHz ARM Cortex-A11 SoC
- 3,5 mm four-pole socket with audio output and "composite video output"
- 40-pin GPIO header.
- Camera interface
- Screen interface
- Micro SD card slot
Raspberry Pi 2
Raspberry Pi 2 is one of the most popular releases of Raspberry Pi. It has been used in most projects. The Pi 1 A and A + models did not have a USB and Ethernet hub. For connectivity, the Raspberry Pi 2 has an Ethernet interface of up to 100Mbps. You also get 4 USB 2.0 ports on the Pi 2 Model B.
Unlike many reviews of the Raspberry Pi 1, the Raspberry Pi 2 had only one revision of the Model B, the Raspberry Pi 2 B. Now, there are not many differences between the Pi 1 B + and Pi 2 B, except for the double amount of RAM (512 MB vs 1 GB) and improved quad-core ARM Cortex-A7 processor with 900 MHz torque.
The Raspberry Pi 2 was also the first Pi to introduce an external distro that charges using an SD card. Note that you must use a class 10 SD card for this purpose. A micro-USB power supply for the Pi, and it is recommended that you use a power outlet.
Raspberry Pi 3
The Raspberry Pi 3 is another very popular board from the Raspberry Pi foundation. The Pi 3 had three revisions - the first was the Pi 3 Model B, the second the Model B + and the third the Model A +.
The Pi 3 Model B is the successor to the Pi 2 Model B. Some of the most important differentiators of the Pi 3 Model B were the upgraded supply rating processor and power source. It was also the first Raspberry Pi to feature Wi-Fi (wireless LAN) and Bluetooth connectivity.
The Pi 3 Model B + is a highly improved version of the Pi 3 Model B. Compared to the Pi 3, it had a faster clock speed (200 MHz faster), introduced Gigabit ethernet via USB 2.0, and added a new Wi-Fi module. -Fi with support for 5 GHz networks.
The Pi 3 Model A was a limited edition Pi 3 Model B +, but with the Raspberry Pi 1 Model A + frame. An excellent table for the construction of works is also accessible IoT.
Raspberry Pi 4
Like the Raspberry Pi 2, the Pi 4 has only one revision, that is, the Raspberry Pi 4 B. As one would expect from the next-generation Raspberry Pi, it comes in 2 GB, 4 GB and 8 GB RAM variants, a huge upgrade from 1 GB RAM of 3 B +. Some of the other upgrades included the introduction of the Gigabit Ethernet port, dual 4K Mini HDMI ports, the addition of 2 USB 3.0 ports, an improved Broadcomm processor with more powerful Cortex-A72 cores, and finally a USB Type-C type for power supply.
Raspberry Pi Hardware
If you are familiar with the Arduino, you will know that you can connect other boards that add various switches, sensors, controls, LEDs, etc. The Raspberry Pi has modules like camera add-on or mini LCD - it is an excellent device for DIY projects.
You can also add a touch screen for Raspberry Pi. If you feel you need it, but you can connect the monitor over a network to another computer using the Terminal SSH or Putty command in Windows.
Raspberry Pi Software
Raspberry Pi uses Linux kernel-based operating systems. The official operating system is based on Debian Linux and is called Raspberry Pi OS.
Always active open source communities always create and support the latest and greatest distributions like Ubuntu / Ubuntu MATE. The community also has LineageOS Android for Pi.
Raspberry Pi is a flexible piece of engineering that could be used in various DIY projects. For example, you can create your own anonymous Tor router, music player, radio, personal VPN, personal web server, connect it to the DSLR, and more.
