Raspberry Pi 3 Model B

OVERVIEW:

The Raspberry Pi 3 is the third generation Raspberry Pi. It replaced the Raspberry Pi 2 Model B in February 2016. Compared to the Raspberry Pi 2 it has:

• A 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.
