Description

• Adapter board to convert a 1602 LCD display to use the I2C interface

• Reduces required pins from 16 to only 2 (SDA & SCL)

• Based on the PCF8574 I/O expander chip

• Adjustable contrast control via onboard potentiometer

• Operating voltage: 5V (compatible with Arduino, Raspberry Pi, ESP8266, and other microcontrollers)

• Ideal for projects requiring LCD displays with fewer I/O pins
