This I2C interface adapter board is designed to simplify the use of a 1602 LCD screen with Arduino or other microcontrollers. Traditionally, driving an LCD1602 display requires 7 digital I/O pins, but with this adapter, only 2 I/O pins (SDA and SCL) are needed thanks to the I2C protocol—saving valuable I/O resources for other components like sensors, relays, or SD cards.
Perfect for compact or I/O-limited projects, this board includes a backlight control and a contrast adjustment potentiometer. Just plug it into the back of a standard 1602 LCD screen, and you’re ready to go with 4 simple wires: VCC, GND, SDA, and SCL.
Features:
Supply Voltage: +5V
Interface: I2C/IIC (SDA & SCL)
I/O Saving: Reduces required pins from 7 to 2
Backlight Control: Built-in control circuit
Contrast Adjustment: Via onboard potentiometer
Compatible with: Standard 1602 and 2004 LCD displays
Easy 4-Pin Connection: VCC, GND, SDA, SCL
Note: This product is only the I2C adapter board. LCD1602 screen is not included.
