Raspberry Pi is a small sized, low cost and power efficient single board computer, with the capability of a high priced desktop computers. You can plugin your mouse, keyboard and a TV or computer screen and you are ready to go. Raspberry Pi is a mobile computer which you can fit in your pocket like your mobile does. It has a processor, RAM, ethernet ports, input and output ports for display (mini HDMI port), keyboard and mouse (USB ports) and power supply port (USB). All-in-all its a complete CPU package. You can install any operating System and use it on-the-go. Because of the powerful processor built-in to its system you can browser web pages, watch HD videos, code and do what you do in your normal computers.
Raspberry Pi is also used as a programmable brain that can interact with the data collected the real world using the sensors and then process it , analyse it or transmit it using internet. It is used all around the world in meteorological departments to log and analyse data. You can choose from range of operating systems to use Raspberry PI. Although, Raspberry Pi has their own flavor of OS you can choose to use.
Raspberry Pi was first release on 24th Feb 2012. Since then it has released five major products in the market and by the year 2019 RP became UK’s top selling single board computer.
Raspberry Pi 4
Raspberry Pi released RP4 with 8 Gigs of RAM on 28th of May 2020. RP4 with 2G, and 4G RAM models were already released in 2019. There is no much of a change in RP’s new release expect for the increase in main memory and the change in the location of usb type-C power supply port. After the announce ment of RP4 8 GB variant new Raspbian OS with 64 bit support was released. Which makes the RP4 harness the 8 Gigs of RAM more efficiently. With Raspberry 4 you can have dual 4k display.

Availability of Raspberry Pi 4 in Nepal
Till date there are no authorized sellers of RP in Nepal but can be found in different retail electronic stores sold independently. Himalayan solution is one of the electronic sellers in Nepal who imports electronic and robotic goods. Himalayan solution provides previos models of RP in discounted amount to engineering students in Nepal. Due to Covid-19 situation it may take a while to import RP4 models but stay tuned with them .
