Standard LCD 16×2 + Extras – White on Blue

This is a common 16×2 character LCD based on the HD44780 controller, giving you 16 characters per line and 2 lines of text. It has white characters on a dark blue background, making text clear and easy to read under normal lighting.

Key specs and features

• Display: 16×2 characters, white on blue positive‑contrast panel.
• Control: Based on the HD44780 controller; can be driven with as few as 6 digital I/O pins (3 for control + 4 for data, or 4‑wire “4‑bit” mode).
• Backlight: Single‑LED backlight, much lower power than older EL‑type backlights; brightness can be adjusted with a resistor or PWM on the backlight pin.
• Connections: 0.1" single‑row header (typically 16 pins), easy to plug into a breadboard; the back of the display often labels the pin functions.

Extra parts included

• Contrast potentiometer: A small trimmer pot to adjust the display contrast for the best readability.
• Header strip: A row of male header pins for soldering to the LCD if it doesn’t come pre‑populated.

Built‑in capabilities

• Character set: Supports standard English/Japanese character sets; full symbols are detailed in the HD44780 datasheet.
• Custom characters: Allows programming up to 8 user‑defined characters, useful for special icons or extended language symbols.

Note: Exact pin‑count and pinout may vary slightly by vendor; always check the manual or marking on the back.
