128*64 dots LCD module 5V with backlight

Description

Graphical display, 128x64px resolution based on the ST7920 controller.

The communication can be done both serial and parallel. Selection is done using the PSB pin (HIGH - parallel, LOW - serial).

In the following example we will use the serial connection (only needs 3 pins).

Pinout: 

Contrast can be set using the V0 pin but this display already has a trimpot on the back.

The backlight is powered using the BLK (cathode) and BLA (anode). It's recommended to add a resistor in series or a potentiometer (2k) if you want to change it later.

The code example attached below, in the Downloads section needs the "U8glib" library.

It can be installed from the Arduino GUI, go to Sketch - Include library - Manage libraries. There search for "U8glib" and install the latest version.
