The 1602 LCD Display with Blue Backlight is a 16-character by 2-line alphanumeric LCD module with a blue-illuminated backlight that produces white text on a blue background — a visually distinct alternative to the green backlight 1602 module that gives projects a cooler, more modern display appearance while using the same HD44780-compatible controller, the same 32 total character positions, and the identical LiquidCrystal library code as the green variant. The lcd 1602 display module with blue backlight is popular with makers and students want their Arduino projects.
The 1602a lcd display module operates on a standard 5V DC supply from the Arduino’s regulated output and connects via the 16-pin HD44780 parallel interface — controlled through the LiquidCrystal library which comes pre-installed in the Arduino IDE and requires no additional download or installation. The lcd 16×2 module fits the standard PCB footprint identical to the green 1602 module, meaning any project enclosure, PCB layout, or panel cutout designed for the standard 1602 size accepts both the blue and green variants interchangeably with no mechanical changes.
The backlight contrast adjustment is done through the contrast pin (VO) connected to a potentiometer to fine-tune white character sharpness on the blue background for different viewing angles and ambient lighting conditions. Available from StemVolt. This lcd display blue backlight module is ideal for Arduino, ESP32 project demo science fair prototype sensor readout and project 1602 blue LCD display.
