Currently, there are several models of Raspberry Pi i.e. A/B, A+/B+, 2, 3 and zero. The differences are on their provided interfaces, RAM size, processor model, processing power, AV jack, etc. Pi 3 uses Broadcom BCM2837 SoC with 64-bit support. Unlike earlier models, Pi 3 has built in wireless support, including 2.4GHz Wi-Fi and bluetooth. There is a Display Serial Interface (DSI) port near GPIO port. There is also Camera Serial Interface (CSI) near HDMI port which provides a high-speed connection to the Raspberry Pi Camera Module. The Pi 3 can draw up up to 1.2A so we need power adapter that can provide 2A of current. Warning : When handling the Pi, always avoid touching GPIO pins, and never connect anything to them while Pi is switched on. GPIO port is powerful but fragile. Software Raspberry Pi Fondation supplies a software tool known as NOOBS (New Out-Of Box Software) which helps user to install standard operating system for Raspberry Pi like Raspbian and others.
