Add 16 more pins that are accessible using I2C easily with this chip. Arduino and Raspberry Pi Compatible
Addding 16 more pins to your microcontroller is easy using this 16 port expander chip. Just communicate to the chip via 2 pins using the standard I2C protocol and you'll have an additional 16 pins that can be inputs, outputs, inputs with a pullup or open drain! Great when your project requires more I/O pins than you have on your Arduino or Raspberry Pi microcontroller.
