What is the Raspberry Pi?
However, in Bangladesh we mean computer, with a system unit, monitor, mouse, and keyboard, a package. In fact, the integral part of a computer is the processor and RAM. I compare the processor to Baburichi, and think of Ram as a patrol. Due to the fact that computing data is composed of two data computing. Now the kitchen and RAM where the kitchen is located (motherboard) is a circuitboard (motherboard). To serve after cooking, it requires a dish (monitor), bowl (printer), cup (speaker). So, a non-profit organization of the British-Raspberry Pie Foundation has made a cookbook, petrol and a small kitchen. That’s the raspberry pie. Its size is slightly larger than the national identity card of Bangladesh. The price is only 35 USD.

There is no distributor of raspberry pie in our country. Founded by the foundation, two foreign companies, Farhanel and RS Computer, produce and market it. Go to their website and purchase it using the international currency card. Delivery will be available at any place in the world subject to shipping fees. Those who do not have the option, they can request relatives and friends living abroad. But many of them have been admitted to the Bangladesh call or private courier. So it is most convenient to buy abroad, with the help of yourself or with someone else.

Let’s say again – this is a computer with a standard-standard one-circuit board. Who has it

Single core processor ARM 700 MHz (can be overclocked)
RAM 512 MB
USB port 2
RJ45 Ethernet port 1
3.5 mm audio out port 1
RCA Video Out Port 1
HDMI port 1
Micro USB port 1 to give power
And the most important GPIO port. I’ll do another tune with it later. I will not write anything about this tune-up GPIO

Only one raspberry pie board above. That is to say, you have to buy several more parts. Many distributors have sold the keyboard, mouse, HDMI cable, power adapter, casing etc. But most of the time, just like the picture above the board is sold and sold. You might have just got the board. However, I have given a brief description of the following things below.

1. Power adapter, which has MicroUSB connector. Founding of 5 volts 700 micro amps (700 mA), Foundation has recommended. Supply of power from the computer or laptop to USB has been discouraged. I used my Samsung Galaxy Y charger. Currently many mobile phones have such chargers.

2. A USB keyboard and mouse – meaning that the keyboard / mouse has the following connectors. Keyboard is not a hunky-punky multimedia keyboard. Because, Ras Pi itself is taking 5 volts, it will be processed from that, now it will not work if you have a keyboard on the USB port.

3. An SD memory card, which has a Linux-based specialized operating system for running this computer. I’ve purchased an already installed SD card. In my opinion, you also purchase similar SD card. SD (micro not included) card is recommended at least 4 GB and data read-write should be high.

4. A television or digital computer monitor. There are RCA components, DVI or HDMI input systems. Can not connect to the widely used VGA port monitors in Bangladesh.

5. According to the type of TV or monitor, there is a need only to connect the raspberry pie. What type of cable will take, depends on your display device type. I’m assuming we’ll connect our home television with Rasp-Pi. That’s why we need, as follows RCA Cable only. Usually red and white colors are used for words, and yellow ends are used for video signals. But it is not matter to us, it is important to have both sides of one color. Radio Corporation America is the inventor of this connector, so its name is RCA connector.

5. There is an HDMI port on the Raspberry pie board. High Definition Media Interface is currently well-known in the HD quality television industry. By using this only we can easily give video conjunction with RASS-PI BOARD to any modern monitor or LCD television. In this case, there will be no need for the above RCA connector. Another thing to note is that both video and audio are available together in the HDMI connection. Meaning, it can be found in some special TV or monitors.

6. For LAN or Internet connection, an RJ45 Ethernet cable is connected to router, switch or hub. Built-in WiFi is not available in RASH-PI. However, the USB WiFi dongle can be worlash it.

7. You can connect headphones or speakers to listen to sounds and psalms from raspberry pie. But as follows, the stereo cone jack will need three and half millimeters. Currently most mobile phones have this type of hole, for headphones to be installed. Therefore, your mobile headphones can be useful. If using the above HDMI cable, this does not require a separate sound jack in the field.
