老早就在关注树莓派这个小东西了，但是没有想到合适的用途所以就一直在观望其实是因为没有钱刚好前几天Diy的群里一位小伙伴要出一台3b，就借着这个机会入手了

树莓派3B简介The Raspberry Pi 3 is the third-generation Raspberry Pi. It replaced the Raspberry Pi 2 Model B in February 2016.

Quad Core 1.2GHz Broadcom BCM2837 64bit CPU

1GB RAM

BCM43438 wireless LAN and Bluetooth Low Energy (BLE) on board

40-pin extended GPIO

4 USB 2 ports

4 Pole stereo output and composite video port

Full size HDMI

CSI camera port for connecting a Raspberry Pi camera

DSI display port for connecting a Raspberry Pi touchscreen display

可以看到，3b的内存是1GiB，同时
