Key Features & Benefits

Effortless Wiring: Uses only 4 pins (VCC, GND, SDA, SCL) to connect to your microcontroller, eliminating messy breadboard connections.

Plug-and-Play Compatibility: Directly compatible with standard 16×2 character LCD modules (with blue or green backlight). Easily solders or plugs onto the LCD’s pin header.

Built-in Contrast Control: Features an onboard potentiometer for precise adjustment of LCD display contrast to achieve optimal viewing clarity.

Wide Voltage Support: Operates on a broad voltage range (typically 3.3V to 5V), making it compatible with both 5V and 3.3V systems.
