DESCRIPTION

The GPIO Expander MCP23017 runs from 3V or 5V logic and power. Each GPIO can be an output driving up to 25mA, so LEDs are no problem. Or, each can be an input, with optional pullup. There are two IRQ pins that are configurable for what inputs to keep track of so no I2C bus polling is required. With 3 address pins, you can have up to 8 on a single bus for a total of 8 x 16 = 128 GPIO all on one I2C bus!

Please note that despite having a row of "PORT A" pins A0-A7, these are digital I/O only, not analog inputs.


FEATURES

  • High Capacity I/O Pins: The MCP23017 serial interface module provides 16 configurable input/output pins, allowing you to expand the I/O capabilities of your main controller. It is perfect for applications that require control over multiple external devices or sensors.
  • Serial Interface: The MCP23017 communicates via the I2C serial interface, 10Mhz serial interface module offering a simple and resource-saving design. This makes it easy to integrate into various projects, providing seamless connectivity.
  • Simplified Configuration: With rich configuration options, the MCP23017 shield module allows you to control the input/output mode, interrupt triggering, pull-up/pull-down resistors, and default input state of the pins through register settings. This simplicity offers flexibility to meet the requirements of different applications.
  • Interrupt Functionality: The MCP23017 I2C IIC serial interface module features interrupt functionality, generating interrupt signals when the pin states change. This is particularly useful for real-time response to external events or input signals, enhancing system efficiency and responsiveness.
  • Wide Application Range: The MCP23017 I/O expander module is widely applicable and can be used in various projects, including robotics, home automation, sensor networks, and more. Its versatility and comprehensive features make it a valuable component for expanding I/O capabilities.
