I2C-Backpack (PCF8574T) for all 5V 1602- and 2004-LCDs with ST7066/HD44780 (16 Pin Interface)
LCD backpacks reduce the number of pins needed to connect to an LCD.
This I2C-Backpack featuring the PCF8574T-I2C-Driver is soldered behind a standard 1602- or 2004-LCD - after that, only 2 I/O-Pins are required to get the LCD up and running. Of course, we provide an Arduino Library for instant and easy operation.
Additionally, you can adjust the constrast with a potentiometer on the backpack, as well as completely disable the backlight with a jumper.
