Description
A new edition of the popular Raspberry Pi minicomputer, version 3. This model features a more powerful processor Broadcom BCM2837 quad-core 64-bit ARM-8 Cortex-A53 with a clock frequency of 1.2 GHz. In addition, the tile has a 1 GB of RAM, integrated wi-fi and Bluetooth 4.1, as well as four USB sockets, 40 GPIO, microSD card slots, an Ethernet port and four mounting holes.
What’s new in version 3?
- The Broadcom chipset BCM2837 with 64-bit core quad-core ARM-8 Cortex-A53 CPU clocked at 1.2 GHz
- Built-in wifi module 150 Mbps 802.11 b/g/n – the latest Raspbian / NOOBs system has built-in controllers
- Built-in Bluetooth system Low Energy BLE 4.1
- The peripheral system remained unchanged, housing for version 2 will be compatible. However, the location of LED diode was changed, so in some housings they can be invisible.
The picture and sound
The Raspberry Pi has HDMI version 1.4, through which you can send both picture and sound. In addition, the tile was equipped with a 4-pin Jack 3.5 mm to connect the headphones, speakers or display video through a standard RCA Composite.
Raspberry Pi 3 model B – top view. The location changed the status LEDs and in their former place is the built-in wi-fi module’s antenna.
Communication
Raspberry has the main communication interfaces, which can be found in office computers of PC class. In addition to the previously listed connectors audio and video, the user has at his or her disposal:
- four of the USB connector,which can connect, for example, a mouse, a keyboard, a wi-fi card or USB flash drive. If you find that the slots are too short, you can increase their number using an external USB HUB.
- Ethernet connector, that is the ability to directly connect to the LOCAL network
- the wi-fi moduleallows communication with wireless network 802.11 b g n – the latest Raspbian / NOOBs system has built-in controllers
- Bluetooth 4.1– provides data transfer through the interface
- GPIO– outputs/inputs of general purpose that can be used to control the LEDs, buttons, controllers of engines. Amongst them are the contacts supporting interfaces: I2C, SPI and UART. Version B+ the GPIO number was increased from 26 to 40.
Power
As a power source, the system uses the microUSB connector. The manufacturer recommends that the voltage indicated on the plug had a value of 5.1 V, and the maximum output current of the used power supply should not be less than 2.5 A.
