MCP23017 I2C 16 Digital IO Expansion Module

Introducing the Lonely Binary MCP23017, an extraordinary IO expansion module that will take your microcontroller projects to new heights. When your IO ports are begging for more, the MCP23017 chip comes to the rescue with its ability to expand an additional 16 IOs. With 8 available I2C addresses, this module allows you to connect up to 8 modules, giving you the potential to expand your IO count to a staggering 128 IOs.

Designed to solve the problem of insufficient IO ports in applications such as robots and interactive medias, the Lonely Binary MCP23017 offers two groups of IO pins: GPIOA and GPIOB. Each group features 8 independent IO interfaces that can be customized for various functionalities, including input, output, pull-up input with a 100KΩ pull-up resistor, and interrupts.

But that's not all! The module also boasts two interrupt signal pins, IA and IB, which detect interruptions in the GPIOA and GPIOB interfaces, respectively. When a pin in either group is interrupted, the corresponding IA or IB pin produces a high-level signal, providing you with precise control and awareness of IO events.

Lonely Binary MCP23017 is more than just a functional module—it's a gateway to limitless creativity. With its expansive IO capabilities and the ease of integration with your microcontroller, you can bring your most ambitious projects to life.
