Adafruit Standard LCD 20x4 + extras

The standard HD44780 LCD, offering 20 characters wide and 4 rows, is perfect for standalone projects with its clear white text on a captivating blue background. Its connection port with a 0.1" pitch, single row design simplifies breadboarding and wiring.

Highlighted by a single LED backlight, it's powered directly from 5V. If the brightness overwhelms, use a resistor or PWM to adjust the dimness, consuming far less power than electroluminescent options. This ensures efficiency without sacrificing functionality.

Control is seamless with just 6 digital lines, supporting English/Japanese text, and up to 8 custom characters for unique glyphs or special language needs. The included contrast potentiometer and header strip enhance usability.

Reference materials available include a datasheet with dimensions and pin-locations, along with the HD44780 datasheet detailing command controls. This ensures a smooth integration process regardless of the specific model variation.
