LCD 16x2 yellow backlight /w I2C

Integrated I2C Serial Interface Adapter: Pre-soldered PCF8574 I2C backpack adapter drastically reduces wiring from 16 parallel pins down to just 4 connection lines (VCC, GND, SDA, SCL).

Standard 16 x 2 Character Layout: Displays up to 32 alphanumeric characters across 2 lines (16 characters per line) for clear system status, dynamic sensor readouts, and debugging.

Warm Yellow-Green Illuminated Backlight: High-contrast STN LCD panel features dark text over a soft yellow-green illuminated background, ensuring reliable readability in dark or low-light environments.

Onboard Contrast Trimmer & Backlight Jumper: Features an integrated multi-turn potentiometer for manual display contrast calibration and a removable jumper for backlight power management.

Standard HD44780 & I2C Library Compatibility: Fully supported by standard microcontroller libraries such as LiquidCrystal_I2C for effortless implementation in Arduino, ESP32, and Raspberry Pi IDEs.

Module Construction: Built on a multi-layer FR-4 glass epoxy printed circuit board featuring soldered I2C backpack board, protective metal bezel, and LCD display matrix.

Power Supply & Operating Voltage: Operates on standard 5V DC logic power. When connecting to 3.3V logic microcontrollers (such as ESP32 or Raspberry Pi Pico), use logic level converters on signal lines (SDA, SCL).

Handling Precautions: Handle carefully by holding the outer board edges. Avoid applying direct force or physical pressure to the central liquid crystal glass panel.

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

Simplified Wiring Selling Point: Highlight the pre-assembled I2C adapter as the main feature, saving users valuable GPIO pins and eliminating breadboard wiring clutter.

Beginner-Friendly Workbench Essential: Position as an ideal starting display module for STEM students, IoT prototyping, and rapid hardware development.

Recommended Cross-Sell Add-ons: Pair with Arduino UNO / Nano / Mega Boards, ESP32 IoT Boards, and Female-to-Female Jumper Wires.

Eye-Friendly Retro Aesthetics: Market the yellow-green backlight as a soft, easy-on-the-eyes alternative to bright blue character displays for custom desktop consoles and monitoring stations.
