PCF8575 16-bit I2C I/O Extension Module for Arduino
A powerful module for Arduino users to expand up to 16 I/O pins while only using two I2C control pins.
Showing last known stock level.
Description
This module is a great solution when I/O pins run out on a microcontroller like the Arduino. The PCF8575 chip is controlled via I2C and allows the user to expand their available I/O count by up to 16 pins, while only consuming two I/O lines for the I2C interface.
