I2C Serial to Parallel Converter for LCD Display for Arduino has PCF8574 I2C chip that converts I2C serial data to parallel data for the LCD display. It can be connected to a standard HD44780 compatible 16x2 or 20x4 Character Display Module that supports 4-bit mode. In general, LCD connection with Arduino require RS, E, and 4 data pins. I2C interface LCD adapter plates leave the flexibility to reduce these pins to only 2. Since it uses I2C mode for communication only SDA and SCL pins are needed. The I2C address is 0x3F by default, but this can be changed via 3 solder jumpers provided on the board.
