Raspberry Pi 3 : WHAT YOU NEED TO KNOW including its LAYOUT

Raspberry Pi 3 was initially developed for educating students on Computer Science.


Raspberry Pi : What is it anyway ?

Its a small light computer sized in the shape of a credit card. Originally developed to be used for education students for Computer-Science, the Raspberry Pi is an immensely favorite among the sea of DIYs, programmers and electronic enthusiasts.

Although this  device is a computer, this device does not include basic peripherals like keyboard,mouse and monitor. You may have to buy some cables and a case for protection to make use of the Raspberry Pi.

But,  the Raspberry Pi does have components to be called a computer such as RAM,USB port,processor and so on. As of today Raspberry Pi  3 is the latest model available. We discussed with  reference to the Raspberry Pi  3 but overall the previous versions are very similar to the recent version.

Here’s a simple list outlining whats on a Raspberry Pi 3-

Overall layout of the latest model of Raspberry Pi 3


  • 1 micro USB power port.Raspberry Pi 3

    For power supply Pi uses a micro USB port and also for charging. A  Micro USB power cord is needed for this. Cell phone chargers  will work. You can also substitute with a  kindle charger if you are short in supply of cell phone chargers. And one more thing- do not  confuse mini USB from micro USB.

  • 1 Ethernet LAN port.

From above, this looks a looks a USB port-but this is the part that will connect to the  internet. You do not need to configure anything  but if you want wireless connection you will need to buy an extra wireless adapter.

  • 1 micro SD card reader

For loading and installing operating system like linux OS. To load your desired Operating system,  Raspberry Pi uses a micro SD card reader as a hard-drive.

SD card is visible underneath the chip-just flip it over.

  • 4 USB 2.0 ports

For connecting input devices and peripheral (like keyboards and mouse).

There are 4 USB ports here. You cant seen them here as they are bricked in pairs over the other. These ports are vital for connecting with your keyboards and other peripherals to make your Raspberry Pi work.

  • 1 3.5mm jack

    This offers both audio and composite video output (you do need to  pair up with the right cable).Raspberry Pi 3

  • 1 HDMI port

The HDMI port is used to connect to a monitor. Use a HDMI cable to make connection with the monitor. If you do no t have a HDMI cable then you can use a RCA cable. An RCA cable is a yellow video cable you see on your TV.

  • 1.2 Ghz ARM processor Systems-On-a-Chip (SoC)

    The processor is  integrated with a  1GB RAM. The  Raspberry Pi 3’s processor is more powerful than the previous versions.

  • 1 Integrated Wi-Fi/Bluetooth radio antenna.

    It took a while to identify this antenna. Its really small but effective.

  • 1 GPIO

    (General Purpose Input/Output) interface.

    Now i need to elaborate what this GPIO really is. The GPIO as you can see has  pins. They are used to  have low-level hardware access directly to the Pi board for  attaching other hardware boards, peripherals, LCD display screens, and  any other hardware devices to your  Pi.


Raspberry Pi : CONCLUSION 

The downside of a  Raspberry Pi ? Well its just that it is not a replacement of your desktop computer or laptop. You can’t run the  traditional  Windows  version, on a Pi but  you can run many distributions of Linux—including distributions with desktop environments, web browsers, and any other elements you would use in a normal Desktop.

If you don’t have  the latest model of Raspberry Pi in hand then fret not. Your still lucky as a star because one can do so much with a Raspberry Pi. One significant different difference between the new and old model is the power. y Pi 3 is much more powerful with better features than the old models. Yet you can do so much with any of Pi models.

In our next post we will talk about all what you can do with a Raspberry Pi. So stay on board the TechTitanic !
