You can check Raspberry Pi 3 B+ which is the fastest and the latest Raspberry Pi model.
Do you want to meet with credit card sized computer Raspberry Pi which is gathering great interest all over the world since it was introduced? Moreover, this model, Raspberr Pi 2, is more powerful and fast than old models. Also Windows 10 IoT works in Raspberry Pi 2.
Raspberry Pi is a credit card sized mini computer board. Even, you can setup it in several minutes and then you can start using it. Just install operating system which one you want to use, to your SD card. Connect your keyboard, monitor and mouse everything is ready to use. The things that you can do with your personal computer, also you can do them with this little computer board. Moreover you can watch HD videos with Raspberry Pi. And yes, all these things are cheaper than 150 Turkish liras.
Many different Linux distributions can be used as operating systems. Now, Raspberry Pi model 2 supports Windows 10 IoT.
The secret hero behind the this board is Broadcom BCM2836 System-on-Chip which is based quad-core ARMv7. This chip has 900MHz clockspeed and Broadcom Videocore 4 GPU. The card can run many applicatios easily because it has 1 GB RAM. Due to GPU's 1080p30 H.264 video decode feature, you can watch BluRay quality videos on your monitor or your TV through to HDMI.
The biggest difference between Raspberry Pi 2 and old Raspberry Pi models is that it has 1GB of RAM instead of 512MB. Raspberry Pi 2 is working on the SD card just like old Raspberry Pi models. You need to install operating system which one you want to use, to the SD card for start to using it. At least 4GB SD card is needed, more woulde be more appropriate.
There are 4 USB ports on Raspberry Pi 2 for connecting keyboard, mouse, wifi dongle or a lot more things on Raspberry Pi. You can increase number of USB ports as much as you want with USB Hub. It is recommended to use USB Hub with external power supply. The power of card comes through a standard micro-usb adapter. It is recommended to use adapter which gives at least 1A output. The quality of adapter is very important for stable operation. It is recommended that the 5V 2.1A Adapter can be used. There is no power button on the Raspberry Pi. It will start working when adapter is plugged.
You can connect to the hardware on the Raspberry Pi through 40-pin GPIO header that located on the board. Those pins are 27 GPIO, I2C,SPI,UART and you can take 5V and 3.3V power from those pins. All I/O pins logic level are 3.3V.
