Part Summary

PCF8574 IIC I2c Serial Interface Adapter Module IIC I2C LCD Module Lcr-t4 5mm Yellow LED Light Emitting2x16 Character LCD is most popular display component for small controller like Arduino, but most of these LCD uses parallel interface. In most of the case, you will need 10 pins to control it or to display message on it. 8 pin are for the data, Enable and Latch pin for signal control. Minimum, you will need 6 pin for 4 bit mode interface. Still a lot of pins being used up :( This I2C module for LCD will help you save all those precious pins. This
