Raspberry Pi 3 Specs

For my project, I used RPi 2. The requirement for my project was WIFI. I had to use an external modem to connect to a network. Sometimes the external modem will not work. Due to the inconsistency, it was hard for me to predict what might work and what might not.



The latest release of RPi 3 is a lot better than the one I've used. Here are the specifications for it.

                          

• A 1.2GHz 64-bit quad-core ARMv8 CPU
• 802.11n Wireless LAN
• Bluetooth 4.1
• Bluetooth Low Energy (BLE)
• 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

RPi 3 has all the wireless connectivity in-built. No external devices are required for it. No extra drivers to be installed. Just have to import a library and then enable it. It's that easy.
