LCD1602 Parallel LCD Display with IIC/I2C interface

An LCD1602 Parallel LCD Display with an IIC/I2C interface combines a standard 16x2 character display with an onboard daughterboard (usually powered by a PCF8574 I/O expander chip). This configuration reduces the number of microcontroller pins required from up to 11 pins down to just 2 pins (plus power and ground), drastically simplifying your wiring layout
