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.
