1601A LCD Display Module

Compact 16 x 1 Character Layout: Displays up to 16 alphanumeric characters on a single line, making it a space-saving option for compact status readouts and simple device telemetry.

Classic Yellow-Green Backlight: Features an STN display matrix with crisp dark text over a vibrant yellow-green illuminated backlight for reliable legibility in various workspace lighting conditions.

Industry-Standard HD44780 Driver IC: Driven by the classic HD44780-compatible display controller, ensuring seamless integration with standard Arduino LiquidCrystal libraries.

Flexible 4-Bit / 8-Bit Parallel Interface: Communicates using standard 16-pin parallel headers, allowing configurable wiring modes to balance GPIO pin usage with signal speed.

Dedicated Contrast Adjustment Pins: Includes onboard solder pads for connecting an external potentiometer to fine-tune screen contrast and text clarity.

Module Construction: Built on a multi-layer FR-4 glass epoxy printed circuit board with standard 2.54mm pin pitch solder pads and a protective metal LCD bezel frame.

Operating Voltage & Logic: Powered by standard 5V DC logic. When interfacing with 3.3V logic microcontrollers (such as ESP32 or Raspberry Pi Pico), use logic level shifters for stable communication.

Handling Precautions: Hold carefully by the outer circuit board edges. Avoid applying direct physical pressure or sharp force to the central glass display surface.

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

Ultra-Compact Alphanumeric Choice: Position as a streamlined alternative to 16x2 displays for projects that only require a single line of status text or simple numeric readouts.

Beginner-Friendly Bench Display: Market as an ideal entry-level screen for STEM students, rapid breadboard prototyping, and DIY hardware debugging.

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

Ideal for Minimalist Dashboards: Great choice for displaying single-line sensor telemetry, digital clocks, system uptime counters, and simple menu options.
