PCF8574 I2C I/O Expansion Module Waterproof reducing error handlingIntroduction : I2C Serial Interface Adapter Module for LCD Display is great Serial Interface Module for interface. As the pin resources of Arduino controller is limited, many project may be not able to use normal LCD shield after connected with a certain quantity of sensors or SD card. However, with this I2C interface module, you will be able to realize data display via only 2 wires. If you already has I2C devices in your project, this LCD module
