    the product works as expected, use the following arduino library: with the settings: #include #include #include #define I2C_ADDR 0x27 // <<----- Add your address here. Find it from I2C Scanner #define BACKLIGHT_PIN 3 #define En_pin 2 #define Rw_pin 1 #define Rs_pin 0 #define D4_pin 4 #define D5_pin 5 #define D6_pin 6 #define D7_pin 7 LiquidCrystal_I2C lcd(I2C_ADDR,En_pin,Rw_pin,Rs_pin,D4_pin,D5_pin,D6_pin,D7_pin); 5 stars for a product which works as expected

    Well packaged, received in good condition and excellent delivery time ( 11 calendar days from order). I generally use this as a general "Port expander" rather than as an LCD back pack. The PCF88574 is super useful and I highly recommend it.

    Very useful with 1602 & 2004 LCD displays. Very easy to connect and solder.

    Very useful item to drive lcd diaplays and other circuits with a reduced number of output pins required from the microcontroller.

    Good value especially as the pack of 5. The one I have used so far came as address 0x3F Good options for fitting a resistor instead of the link for the back-light and the address can be changed slightly by soldering links. Shipped with each interface in an anti-static bag Worked fine with easily found library and using simple lcd commands.
