Description
MCP23017 I/O Expansion Module is a high-speed, professional-grade solution for expanding the input/output capabilities of your microcontrollers like Arduino, Raspberry Pi, and ESP32. If your project requires more LEDs, sensors, or buttons than your board can handle, this 16-bit I2C interface module is the most efficient hardware upgrade available.
Simple 2-Wire Communication
By utilizing the I2C protocol, this module communicates with the main controller using only two pins (SDA and SCL). This minimizes hardware complexity and leaves other pins free for critical tasks like PWM or Analog sensing. It is a must-have component for any integrated circuit tool kit.
Scalable and Configurable Design
One of the standout features of the MCP23017 chip is its configurable hardware address. By adjusting the address pins, you can chain up to eight MCP23017 I/O Expansion Modules on the same I2C bus. This allows for a massive expansion of up to 128 I/O pins, making it ideal for complex industrial automation or large-scale LED matrices.
