1604 Backlight Blue LCD 16X4

Expanded 16 x 4 Alphanumeric Layout: Displays up to 64 characters across 4 lines (16 characters per line) for displaying rich telemetry, detailed status readouts, and multi-line menus.

Vibrant Blue Backlight with Crisp White Text: High-contrast STN display matrix ensures clear, legible character output in low-light and bright indoor environments.

Industry-Standard HD44700 Compatible Driver: Powered by the standard HD44780 controller, making it instantly compatible with the standard LiquidCrystal library in the Arduino IDE.

Flexible 4-Bit / 8-Bit Parallel Bus: Supports both 4-bit and 8-bit parallel communication modes to adapt to available microcontroller pin configurations.

Built-in Backlight & Contrast Control: Features dedicated pins for LED backlight power and variable contrast adjustment via external potentiometer.

Module Construction: Built on a multi-layer FR-4 glass epoxy printed circuit board featuring clear silkscreen labels and standard 2.54mm pitch header pins.

Operating Voltage & Logic: Operates on standard 5V DC logic. Use logic level shifters when interfacing with 3.3V microcontrollers to ensure stable operation.

Handling Precautions: Avoid applying direct pressure or force to the LCD glass panel. Power down circuits before making or adjusting header connections.

Environmental Limits: Operating temperature range spans -10°C to +60°C. Keep protected from static discharge, metallic dust, and direct liquid exposure.

Double the Display Area of 1602: Position as a direct upgrade for customers who have outgrown standard 16x2 LCDs and need twice the screen real estate for complex data.

Ideal for Custom Control Consoles: Highlight as a go-to display for 3D printer interfaces, CNC controller boxes, smart weather stations, and audio equipment menus.

Recommended Cross-Sell Add-ons: Pair with PCF8574 I2C Backpack Adapters (to convert wiring down to just 2 pins), 10K Ohm Potentiometers, and Arduino UNO/Mega Boards.

Clean Text Readout Solution: Position as a low-cost, reliable alternative to graphical displays when simple, highly readable text communication is needed.
