A common application is to add a push button to a Raspberry Pi. Inserting a push button between a 5V or 3.3V pin and a ground pin, effectively creates a short when the button is pushed. Because there is no load between the voltage source and ground. The same happens when a GPIO pin is used for 3.3V output (or input). Since MCP23017 is powered by +5V, the output pins show +5V when they are set to logic high. The +5V voltage rail on the Raspberry Pi expansion header is not subject to a 50 mA limit as is the case for +3.3V voltage rail, providing more latitude for power consumption. Pins 3 and 5 are pulled up on the board to the 3.3V supply by 1.8 KΩ resistors to enable them to be used easily as I2C communication pins. Finding your board's revision number To determine the revision number for your board you can execute the following command from a prompt in a terminal window, For all the programs and circuits discussed here, I have used Raspberry Pi 3.
