LCD 128x64

LCD display module with green/blue backlight. Wide viewing angle and high contrast and can display 128-lines * 64-characters. Small and light appearance, easy and convenient to use. The display is fully programmable and can display a combination of both graphics and text. It can operate in both parallel and serial (SPI) modes which can be configured by the external pin PSB. In SPI mode only 3 data pins are required to drive this display. No potentiometer is required to set the contrast as this is pre set by the factory to optimum level.
