IIC I2C TWI SPI Serial Interface Board Module Port for Arduino LCD1602 Display

This is a I2C Serial LCD Daughter board that can be connected to a standard 16×2 or 20×4 Character Display Module that supports 4-bit mode. All Character Modules sold on our site support 4-bit mode, and nearly all commercially available 16×2 and 20×4 line character modules support it too. This board has a PCF8574 I2C chip that converts I2C serial data to parallel data for the LCD display.
