Pi 3 Model B在Pi 2 Model B基础上的改进：
- Next Generation QUAD Core Broadcom BCM2837 64bit processor
- Processor speed has increased from 900MHz on Pi 2 to 1.2Ghz
- BCM43438 WiFi on board
- Bluetooth Low Energy (BLE) on board
- Upgraded switched power source up to 2.5 Amps (can now power even more powerful devices over USB ports)
其他技术规格：- 40pin extended GPIO
- 4 x USB 2 ports
- 4 pole Stereo output and Composite video port
- Full size HDMI output

入门问题解答：
What software will be made available and where can I download it?
New software is available for download on the Raspberry Pi Foundation’s website. Please visit: http://www.raspberrypi.org/downloads/ for the latest Pi software.
Alternatively, you can purchase a Raspberry Pi 3 Model B with a 16GB NOOBS MicroSD card with the software pre-loaded to ease getting started. See our accessories listing for full details.
How do I get the built-in WiFi and Bluetooth connectivity to work with the Raspberry Pi 3 Model B?
IMPORTANT: To enable the built-in WiFi and Bluetooth connectivity you will need to update the operating system on the card to the latest version. On first boot please click on the ‘Terminal’ icon and type:
sudo apt-get update
sudo apt-get upgrade
What versions of Bluetooth and Wi-Fi are supported?
The new Raspberry Pi 3 supports BLE (Bluetooth Low Energy 4.1) and Wi-Fi 802.11 b/g/n.
Will the 16GB NOOBS MicroSD Card I receive work with other models?
Yes, it will be backwards compatible.
Will the microSD card and Operating System from my previous model of Raspberry Pi work with the Raspberry Pi 3 Model B?
No, if you are using Raspbian you will have to update it first. On your existing Raspberry Pi you can run the following commands from the terminal:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade Alternatively, you can download the latest SD Card image from raspberrypi.org/downloads.
Will the Raspberry Pi support more than just the Raspbian operating system?
Yes, the Raspberry Pi already supports 7 official operating systems including:
- Raspbian
- Windows 10 Core IoT
- OpenELEC
- OSMC
- Arch Linux
- RISC OS
- Pidora
Is WiFi and/or Bluetooth available on earlier models of the Raspberry Pi?
This functionality is not built-in to the previous models (Pi2, B+, etc.), but you can gain access to WiFi and Bluetooth by using an appropriate USB dongle (we recommend the WiPi dongle).
Can the Pi 3 be overclocked?
Overclocking the Raspberry Pi 3Raspberry Pi 3 is not recommended and you may void your warranty attempting to do so.
Is the Raspberry Pi 3 benefiting from ARMv8 or ARMv7 architecture?
The Raspberry Pi 3 uses the latest BRCM2837 processor, containing a quad 64 bit A53 processor running at 1.2GHz. The processor instruction set is compatible with the ARMv8-A architecture which includes backwards compatibility with the previous ARMv7-A architecture. The Raspbian distribution will only support ARMv7-A instruction set but other distributions will be able to take further advantage of the ARMv8-A instructions and 64 bit support.
Is there a size limit on the microSD Card with the new board?
We have successfully tested cards up to 64GB with the new Raspberry Pi 3 board.
What power supply do I need?
We recommend you use the new official 5.1V, 2.5A Raspberry Pi power supply。This power supply will enable users to power their Pi and other accessories from one power source, thus maximising the benefits of the Pi 3’s improved power management capabilities.
Where can I find schematics for the new model?
We do not issue schematics.
