MCP23017 - I2C 16 Input/Output Port Expander GPS Antenna 2 MB SPI FLASH chipAdd another 16 pins to your microcontroller using an MCP23017 port expander. The MCP23017 uses two I2C pins (which can be shared with other I2C devices) to provide 16 general purpose pins. Each pin can be set as input, output, or input with a pullup resistor. Additionally, an interrupt can be generated via an external pin when any of the inputs change, eliminating the need for constant polling. This chip operates with a voltage range of 2. 7 5. 5V,
