Easily add a crisp display to your electronics project in no time—without sacrificing all your GPIO pins. This 1602 LCD Display Module comes equipped with a pre-soldered I2C interface (PCF8574). Instead of dealing with 16 individual pins, you only need 4 wires to fully control the screen!

The display can show up to 32 characters at once (16 characters per line across 2 lines) and features a blue or green backlight with adjustable contrast via the built-in potentiometer on the back.

Why choose the I2C version?

• Plug & Play: No messy wiring or soldering required; ready to use right out of the box.

• Save GPIO Pins: Uses only 2 data communication pins (SDA & SCL) on your microcontroller.

• Easy Programming: Works seamlessly with popular Arduino libraries such as LiquidCrystal_I2C.h.

• Adjustable Contrast & Backlight: Built-in potentiometer on the back for optimal readability and a jumper to turn the backlight on or off.
