GPIO Pinout

The Raspberry Pi offers up its GPIO over a standard male header on the board. Over the years the header has expanded from 26 pins to 40 pins while maintaining the original pinout.


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)

 The same form factor as the Pi 2 Model B, - the only difference is the location of the onboard LEDs
