LCD 16x2 Black on Green 5V - I2C

This is a 16x2 display with black text on green background that comes with the I2C backplate. You only require 4 wires to control the display and With the limited pin resources your project may be out of resources using a normal LCD shield. With this I2C interface LCD module, you only need 2 lines (I2C) to display the information.

I2C Address Setup

Arduino I2C Display

The LCD2004 board utilized the PCF8574 I/O expander. This nifty little chip provides eight bits of parallel I/O addressable by a I2C bus address – 0x00 to 0x27. SainSmart tied all address leads to Vcc, so the LCD2004 board’s I2C address is permanently fixed at hex 27. This is rather limiting since no additional LCD2004s can be added to the bus. Anyway, you simply address the board and write an eight bit value which is then presented on the output pins of the PCF8574, which, in this case, are connected to the HD44780 based LCD screen.
