Description of product: Raspberry Pi Model B 512 MB RAM
The Raspberry Pi device was developed as alternative to large and expensive computers. Insituationsthat do not require large computing capacity, and requirements posed by equipment is, first of all, the compact size and low power consumption, the raspberry works fine. This miniature computer has aperformance level of a Pentium II, but for normal work it is enough only a screen (monitor or TV),memory card,power supply microUSB(or, for example, a charger for the phone) anda computer keyboard.In the case of using graphics, you should also connect amouse.

Built-in DC JackHDMIallows you to connect a TV or monitor, and broadcast in theresolutionFull HD (1080p). In the absence of HDMI, the user has at its disposal an RCA Jack (popular Auto).
Sound
Audio is via a 3.5 mm Jack that are used in popular speakers and headphones. Sound can also be transmitted through cableHDMI, if the TV or monitoris equipped withwas momentum.
Data carrier
The creators Rasbpery Pideclinedfrom the hard drive. His roletook ona much easier, less emergencySD memory card. With this solution the computer is lightweight and consumes much less energy. Through the card, install the operating system, in addition, it serves as a place to store data.
Link
Raspberry is the main communication interfaces, which can be found in office computers of class PC. In addition to the previously listed connectors audio and video the user has at his disposal:
- two USB ports,which can connect, for example, a mouse, keyboard or USB flash drive. If you find that the slots are too short, you can increase their number usingan external USB HUB
- Ethernet connector, that is the ability to directly connect to the LOCAL network
- Wi-Fi- in our offer there is also awireless network card is USB,thanks to which Raspberry can connect to a Wi-Fi network
In addition, the system includes interfaces that are typical for systems based on mikrokontrolerach. This:
- GPIO- outputs/inputs General purpose, can be used to operateLEDs,buttons,drivers, engines
- PiFace- in our offer there is also a modulePiFacefunctionality in GPIO ports,
- the I2C busallows communication with various sensors (e.g.,temperatureoracceleration),
- Gertboard- a module, expanding the capabilities Raspbery Pi, in particular, on the ability to controlDC motor, transducers, A/C and additional GPIO pins
- SPI- allows you to connect quick converters analog-to-digital and different types of memory,
- UARTis a popular, simple serial interface.
Food
As a power source, the system uses the microUSB connector. In practice, this means that running Rasbperry Pi youuse, the popular smartphone in the world,the chargerwith the connector.
Operating system
In order to install the operating system just a connectorfor SD cardson the computer and the Internet. In order to download opogramowania and the file that contains the virtual operating system image, you need to go tothe project page. Then use the downloaded software to install the image on the memory card. The whole procedure is quick and uncomplicated, we have prepared a briefmanual,then install the operating system.
Raspberry Pi works among other with the following operating systems:
- Raspbian
- Debian GNU/Linux
- And Linux ARM
- RISC OS
- AROS
- Android 4.0
- FreeBSD
- Gentoo Linux
- Google Chrome OS
- Slackware ARM
Accessories
The Raspberry Pi, and any PC, requires some basic accessories to work with. Most of them we have in our offer:
- keyboard- as a primary means for data entry,
- SD memory carddrive, Raspberry,
- HDMI cable- it can connect the device to the monitor,
- A USB huballows you to expand the number of USB ports (default, two),
- housing- will protect minikomputer from the external environment
- PiFacemodule extends the capabilities of the GPIO ports
- Gertboard- a module, expanding the capabilities Raspbery Pi, in particular, on the ability to controlDC motor, transducers, A/C and additional GPIO pins
- Power- power supply with microUSB connector, allowing you to run minikomputer
