MCP23017 I/O Expander Module - Bidirectional 16-Pin dfr0523 Adafruit HUZZAH CC3000 WiFi ShieldI O ports play a significant role in microcontrollers' functionality as it is the gateway for devices to be operated, as well as to read data from sensors. A microcontroller has a limited number of I O pins, but there is a way to get more of these pins for a larger project. This MCP23017 chip is an I O expander that could add 16 I O pins to your microcontroller. You can set each pin as an input or output, or an input pullup. You can even get an
