Adafruit Graphic ST7565 Positive LCD (128x64) w/RGB Backlight + Extras

This graphical display looks great, costs less! The dark gray pixels are visible in daylight, and there's also a full RGB LED backlight, which you can control with PWM to make any color you can imagine. Four mounting holes and a blank 11 pin 2mm-pitch labeled breakout on the side - we just soldered some wire to each hole as shown in the photos, its very easy. (The LCDs have no wires soldered in when we ship them) Bonus! We're including a free 4050 level shifter chip so that you can safely use it with your favorite 5V microcontroller Advantages!

• Lower cost than KS0108 LCDs
• Serial interface uses only 4 or 5 digital pins
• Low power, full-color RGB LED backlight
• Visible in daylight without backlight
• Works perfectly with 3V logic

Challenges!...

• 3.3v power and logic means a level converter is needed for 5V Arduinos (we include this part when purchasing from us)
• Microcontroller must buffer display - uses 1Kb of RAM. This means you must upgrade to a ATmega328 if you are using an Arduino with a '8 or '168

See here for a more detailed tutorial, including how to wire up the display with a 4050. There is a C code and an Arduino library ready to go (we suggest reading the above tutorial too!)
