Description:
LCD1602 is an industrial character LCD that can display 16x2 or 32 characters at the same time.
The principle of the LCD1602 LCD is to control the display area by voltage by utilizing the physical properties of the LCD, which means it displays graphics.
The 1602 uses a standard 16-pin interface, and the display module is a module that provides I2C functionality.
The I2C only uses two two-way open drain lines, Serial Data Line (SDA) and Serial Clock Line (SCL) that are pulled up with resistors. Normal voltage is +5V or +3.3V but other voltage systems are permitted. It can work if you support I2C development board.
For example, the common Ar-duino, Raspberry pi, Stm32 etc.
Features: Easy to use. Less I/O ports occupy. Support IIC protocol I2C LCD1602 library is easy to find. With potentiometer used to adjust backlight and contrast. Yellow backlight Power supply: 5v; I2C address is 0x27
