The LCD I2C Module PCF8574 is a small circuit board that allows you to connect a standard Alphanumeric LCD displays 1602 & 2004 to an I2C bus. This means that you can control the LCD display with only two wires, SDA and SCL. The PCF8574 is an I2C slave device, so it has a unique address on the I2C bus. This address can set using three jumpers on the board.

The LCD I2C Module PCF8574 is compatible with most 16X2 and 20X4 character LCD displays that use the HD44780 controller. The board also has a potentiometer for adjusting the contrast of the LCD display.

LCD I2C Module PCF8574 can operate with an input voltage of 2.5 to 6 volts. The typical input voltage is 5 volts. The module has a regulator that converts the input voltage to 5 volts for the LCD display.

The PCF8574T IC chip on the module is an I2C slave device. This means that it can receive commands from a master device, such as an Arduino. The module has a 7-bit address that can set using jumpers on the board. The LCD I2C Module PCF8574 works on the I2C (Inter-Integrated Circuit) communication protocol. This protocol allows two devices to communicate with each other using only two wires: SDA (Serial Data) and SCL (Serial Clock).

The module also has a potentiometer that is used to adjust the contrast of the LCD display. The contrast is the difference between the light and dark pixels on the display. By adjusting the potentiometer, you can make the dark pixels darker and the light pixels lighter.

The LCD I2C Module PCF8574 is a great way to add a display to a project without having to use a lot of pins on a microcontroller. It is a relatively simple device to use, and it can control by using the I2C communication protocol.
