The DIP-28 MCP23017 already in the catalog is the easy breadboard-friendly way to add 16 extra GPIO pins to an I2C bus, expanding far beyond what a microcontroller's own pin count allows for driving relays, reading switches, or controlling an LED matrix. This SOIC-28 version puts the exact same genuine Microchip chip and I2C interface into a surface-mount footprint, meant for a finished PCB design rather than a prototyping breadboard.
