Raspberry Pi 3 Model B The Pi 3 is exactly what you would expect from the latest Raspberry Pi. No, it doesn’t have SATA or USB C or a PCIe connector. The goal of the Raspberry Pi Foundation has always been to produce an inexpensive computer for everyone, and adding these ports would only drive up the price. Instead of pleasing the power users, the Pi Foundation has done their best to please anyone. Like the Raspberry Pi 2 from late last year, the Raspberry Pi 3 features a new CPU, a Broadcom BCM2837 quad-core 64-bit ARM Cortex A53 running at 1.2 GHz.

Key Improvements from Pi 2 Model B to Pi 3 Model B:

• Next Generation QUAD Core Broadcom BCM2837 64bit processor
• Processor speed has increased from 900MHz on Pi 2 to 1.2Ghz
• BCM43438 WiFi on board
• Bluetooth Low Energy (BLE) on board
• Upgraded switched power source up to 2.5 Amps (can now power even more powerful devices over USB ports) Other Technical Specification:
• 40pin extended GPIO
• 4 x USB 2 ports
• 4 pole Stereo output and Composite video port
• Full size HDMI output
• CSI camera port for connecting the Raspberry Pi Camera
• DSI display port for connecting the Raspberry Pi touch screen display
• Micro SD port for loading your operating system and storing data
• Upgraded switched Micro USB power source (now supports up to 2.5 Amps)
