198 Adafruit Standard LCD 20x4 + extras - white on blue
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 included 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
