The Raspberry Pi 3 is the third generation Raspberry Pi. It replaced the Raspberry Pi 2 Model B in February 2016.
RASPBERRY PI 3 MODEL B
Website: https://www.raspberrypi.org/
Compared to the Raspberry Pi 2 it has:
1.2GHz 64-bit quad-core ARMv8 CPU
802.11n Wireless LAN
Bluetooth 4.1
Bluetooth Low Energy (BLE)
Like the Pi 2, it also has:
1GB RAM
4 USB ports
40 GPIO pins
Full HDMI port
Ethernet port
Combined 3.5mm audio jack and composite video
Camera interface (CSI)
Display interface (DSI)
Micro SD card slot (now push-pull rather than push-push)
VideoCore IV 3D graphics core
The Raspberry Pi 3 has an identical form factor to the previous Pi 2 (and Pi 1 Model B+) and has complete compatibility with Raspberry Pi 1 and 2.
We recommend the Raspberry Pi 3 Model B for use in schools, or for any general use. Those wishing to embed their Pi in a project may prefer the Pi Zero or Model A+, which are more useful for embedded projects, and projects which require very low power.
不熟悉 Raspberry Pi？
Raspberry Pi 是单计算机板 - 开发用于鼓励和帮助编程和计算的教学。 它还是开发物联网 (IoT) 项目的极佳起点。 Pi 的低成本和“即插即用”特性催生了可访问一切的板，并具有各种连接选件。 Pi 是完美的实验工具，无论您想要将其用作台式计算机、媒体中心、服务器还是您家中的监控/安全设备。 一切皆可实现。 基于 Linux 的操作系统在 Pi 上运行，可访问大量免费软件和下载文件。
