The MCP23017 I2C to 16 IO Expander Breakout provides 16 additional I/O pins via an I2C interface, ideal for expanding microcontroller GPIO capabilities without additional complex wiring. It allows for individual configuration of each pin as input or output and includes interrupt support for enhanced functionality. Compact and easy to integrate, this module is suitable for projects requiring multiple digital I/O, such as home automation, robotics, and control systems.
Key Features:
-
16 I/O Pins: Expands 2 signal pins into 16 fully configurable I/O pins.
-
Multi-board Expansion: Stack up to 8 boards to achieve up to 128 I/O pins for larger projects.
-
I2C Address Configuration: Customize I2C addresses by adjusting A0, A1, and A2 jumpers.
-
