DESCRIPTION
This LCD display module has wide viewing angle and high contrast. It comes with pre-soldered resistor on the contrast and backlight pins so you don't have to worry about getting an external potentiometer to adjust the contrast and you can drive the backlight with 5V directly. LCD display is 128 lines by 64 characters. It is 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 PSB pin. In SPI mode only 3 data pins are required to drive this display.
**Note: Pin headers are not included, please purchase them separately.
