    Want to print this out for use on your header? I saved the image to my PC. Open with MSPaint. Go to Page Setup. Change your scaling to 18%. Print the image. Cut it out and press in place on your GPIO header…

    clem57 I fully realize that you are not responsible for the RPi's deficient docs. And I thanked you earlier for your contribution to try to fill in the blank. You seem to think I'm criticizing you and…

    I agree. It is quite moving that Element14's entire team, and Farnell/Newark, clem57 and others in the community do such a fantastic job supporting as best as they can, and get people up-to-speed on the…

    I'll have a legend on the next version, thanks.

    Hi Sean,

     

    Green appears to be general-purpose pins, orange is UART, blue is I2C, purple is SPI. Yellow is a second I2C bus sometimes connected to an EEPROM.

    Awesome reference. Where is the legend for the pin colours? Pins are grouped together in colours. I was looking for a translation.

    Hi Guy,

     

    As long as you're careful, then yes you can apply 5V to pins 2/4 (either or both) and GND to (say) pins 6 or 14 or both.

    You're bypassing some protection by doing this, but it will operate the Pi.

    You mention a battery, but usually a battery has a voltage other than 5V. Provided it is regulated to 5V (e.g. a mobile phone portable battery-powered charger), then this will work.

    Can you power the pi from pins 2 and 4.  I currently am powering a touch screen from pin 2 but would like to use pin 4 to provide power from a battery.  I would think you can but I don't want to hurt the pi.
