Different Types of Raspberry Pi Boards Models and Its Uses

 The name Raspberry Pi is derived from the fruit pie, raspberry pie. This is because many companies in the computer neighborhood where Raspberry Pi was based used fruit names such as Apple and apricot as names for their companies and products. The main intention of this foundation is to develop the education system for children and adults, especially in the field of computer science-related subjects. The Raspberry Pi is a credit card-sized and low-cost device. It plugs into a TV or computer monitor and uses a mouse and keyboard. This device allows all the students and aged people to learn how to write a program in a language like Python and Scratch. This Raspberry Pi is mainly used for browsing the internet, playing HD video, word pressing, playing games, and making spreadsheets. The applications of Raspberry Pi are mainly involved in digital projects, music machines, weather stations, IR cameras, and raspberry pi projects. What is Raspberry Pi? Generally, the raspberry pi is designed for educational purposes and it is in a small size as a credit card. It will improve the programming skills & hardware programming at the higher education in the schools or colleges. The raspberry pi is slower than the laptop or desktop and it is totally in the Linux operating system. The availability of prices in the market is low. The Type of Architecture Used in Raspberry Pi The processor now uses the Cortex-A72 architecture (quad-core 64-bit ARMv8 at 1.5GHz). It supports H. 265 hardware video decoding for instance. The Raspberry Pi has been stuck at 512MB or 1GB of RAM for years. The Raspberry Pi board used in many Sector The Raspberry pi is a single computer board is an amazing kit to help you learn computer science, programming, electronics with credit card size, that can be used for many tasks that your computer does, like games, word processing, spreadsheets and also to play HD video. Let’s see the family of Raspberry PI Complete Kit India, which is started with Raspberry Pi 2 , Raspberry Pi 3 Model, Raspberry Pi 4 Model The Raspberry Pi 2 was released in February 2015 and initially featured a 900 MHz 32-bit quad-core ARM Cortex-A7 processor with 1 GB RAM. Revision 1.2 featured a 900 MHz 64-bit quad-core ARM Cortex-A53 processor (the same as that in the Raspberry Pi 3 Model B, but underclocked to 900 MHz). Raspberry Pi 3 Model was released in February 2016 with a 1.2 GHz 64-bit quad-core ARM Cortex-A53 processor, onboard 802.11n Wi-Fi, Bluetooth, and USB boot capabilities. On Pi Day 2018, the Raspberry PI 3 Model B+ was launched with a faster 1.4 GHz processor, a three-times faster gigabit Ethernet (throughput limited to ca. 300 Mbit/s by the internal USB 2.0 connection), and 2.4 / 5 GHz dual-band 802.11ac Wi-Fi (100 Mbit/s). Other features are Power over Ethernet (PoE) (with the add-on PoE HAT), USB boot, and network boot (an SD card is no longer required). Raspberry Pi 4 Model was released in June 2019 with a 1.5 GHz 64-bit quad-core ARM CortexA72 processor, on-board 802.11ac Wi-Fi, Bluetooth 5, full gigabit Ethernet (throughput not limited), two USB 2.0 ports, two USB 3.0 ports, 2-8 GB of RAM, and dual-monitor support via a pair of micro HDMI (HDMI Type D) ports for up to 4K resolution. The Pi 4 is also powered via a USB-C port, enabling additional power to be provided to downstream peripherals, when used with an appropriate PSU. The initial Raspberry Pi 4 board has a design flaw where third-party e-marked USB cables, such as those used on Apple MacBooks, incorrectly identify it and refuse to provide power. Tom's Hardware tested 14 different cables and found that 11 of them turned on and powered the Pi without issue. The design flaw was fixed in revision 1.2 of the board, released in late 2019. Raspberry Pi 400 Kit Raspberry Pi 400 was released in November 2020. It features a custom board that is derived from the existing Raspberry Pi 4, specifically remodeled with a keyboard attached. The case was derived from that of the Raspberry Pi Keyboard. A robust cooling solution similar to the one found in Commodore 64 allows the Raspberry Pi 400's Broadcom BCM2711C0 processor to be clocked at 1.8 GHz, which is slightly higher than the Raspberry Pi 4 it's based on. The keyboard-computer features 4 GB of LPDDR4 RAM. Raspberry Pi Zero • A Raspberry Pi Zero with a smaller size and reduced input/output (I/O) and general-purpose input/output (GPIO) capabilities was released in November 2015 for US$5. • On 28 February 2017, the Raspberry Pi Zero W was launched, a version of the Zero with Wi-Fi and Bluetooth capabilities, for US$10. • On 12 January 2018, the Raspberry Pi Zero WH was launched, a version of the Zero W with pre-soldered GPIO headers. Raspberry Pi Pico Raspberry Pi Pico was released in January 2021 with a retail price of $4. It was Raspberry Pi's first board based upon a single microcontroller chip; the RP2040, which was designed by Raspberry Pi in the UK. The Pico has 264 KB of RAM and 2 MB of flash memory. It is programmable in MicroPython, CircuitPython, and C. It has partnered with Vilros, Adafruit, Pimoroni, Arduino, and SparkFun to build Accessories for Raspberry Pi Pico and a variety of other boards using RP2040 Silicon Platform. Rather than perform the role of a general-purpose computer (like the others in the range) it is designed for physical computing, similar in concept to an Arduino.
