2x MCP23017-E/SP I2C I/O Expander – 16-Bit DIP-28 IC For Arduino & Raspberry Pi Projects
About this item
Need more pins for your microcontroller project?
Grab this 2-pack of MCP23017-E/SP I/O expanders.
They're brand new, unused, and ready to solder into your next breadboard or PCB.
These chips give you 16 extra I/O pins over an I2C interface, which is a lifesaver when you're running out of pins on your Arduino or Raspberry Pi.
They come in the classic DIP-28 package, so they're perfect for prototyping or permanent builds.
Since they're generic/unbranded, you're just paying for the silicon that does the work—no fancy packaging, just solid performance.
Whether you're building a smart home controller, a robot, or just playing around with LEDs and sensors, these expanders are a reliable way to scale up your inputs and outputs without complicating your code.
