Raspberry Pi GPIO Pins

I’ve just started playing around with Raspberry Pi and Arduino. I should be studying for my CCNA, but I need a break before I get burned out, besides, it’s a lot of fun.

For the Raspberry Pi, I ordered a kit from Cana Kit, which came with a nice little reference card for the GPIO (General Purpose Input Output) pins on the board, but I found it to be a bit confusing. There are several others available online, but they all suffer from the same issue, they are not color-blind friendly. Being color-blind myself, I find these references more than a little difficult to work with. So after doing some research into the GPIO pins, I designed my own, color-blind friendly, GPIO reference sheets. There are 5 sheets in all. One for BCM (Broadcom, the default), one for WiringPi, one for I2C, one for SPI and the final one contains all of the other 4 rolled into one. I’ve left the 3.3V, 5V and GND pins labeled on each sheet, you may find them useful as reference points.

You can get the sheets from the links below, if you’re interested. Each sheet is available in a U.S. Letter size PNG or PDF.

I hope you find these useful.
