1602 Yellow LCD Display Module

Standard 16 x 2 Character Layout: Displays up to 32 alphanumeric characters across 2 lines (16 characters per line) for clear system status updates, sensor readings, and diagnostic messages.

Warm Yellow-Green Backlight: Equipped with an LED backlight that provides high-contrast, dark-character visibility on a warm yellow-green background, comfortable for extended viewing.

Industry-Standard HD44780 Controller: Powered by the standard HD44780 display driver, making it instantly compatible with the native LiquidCrystal library in the Arduino IDE.

Flexible Parallel Interface: Supports both 4-bit and 8-bit parallel communication modes to accommodate available microcontroller digital I/O pins.

Integrated Contrast & Backlight Pins: Features dedicated pin headers for adjustable screen contrast (via external potentiometer) and independent LED backlight control.

Module Construction: Built on a multi-layer FR-4 glass epoxy PCB with standard 2.54mm header pin solder pads and a protective LCD panel bezel.

Operating Voltage & Logic: Operates on standard 5V DC logic power. Use logic level shifters when connecting to 3.3V boards (like ESP32 or Raspberry Pi Pico) to ensure reliable operation.

Handling Precautions: Hold carefully by the edges of the circuit board. Avoid placing direct pressure or physical force on the central liquid crystal display screen.

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

Classic Maker Display Pitch: Position as the quintessential entry-level screen for electronics hobbyists, STEM classrooms, and initial hardware prototyping.

Warm Visual Alternative: Highlight the yellow-green backlight as a soft, retro-style visual alternative to standard high-brightness blue LCDs.

Recommended Cross-Sell Add-ons: Pair with PCF8574 I2C Backpack Modules (to reduce pin usage down to just 2 wires), 10K Ohm Potentiometers, and Arduino UNO / Nano Boards.

Ideal for Everyday Telemetry: Perfect choice for custom desktop weather stations, digital clocks, water flow monitors, and basic system diagnostics.
