Adafruit – Standard LCD 20×4 + Extras – White on Blue

Adafruit: 198

Description

Standard HD44780 LCDs are useful for creating standalone projects.

• 20 characters wide, 4 rows
• White text on blue background
• Connection port is 0.1″ pitch, single row for easy breadboarding and wiring
• Single LED backlight with a resistor included, you can power it directly from 5V. If it’s too bright for you, it can be dimmed easily with a resistor or PWM and uses much less power than LCD with EL (electroluminescent) backlights
• Can be fully controlled with only 6 digital lines!
• Built in character set supports English/Japanese text, see the HD44780 datasheet for the full character set
• Up to 8 extra characters can be created for custom glyphs or ‘foreign’ language support (like special accents)
• Comes with necessary contrast potentiometer and strip of header

We have a generic 20×4 datasheet that has dimensions and pin-locations (the exact model may vary but the pinout, size and protocol information is the same). We also have a HD44780 datasheet with the detailed commands for control.
