ST7290 Graphical LCD Module

This Graphical LCD is having low power consumption and also suitable for battery power portable device. It have wide operating voltage range 2.2v to 5.5v and supports both serial and 8/4-bit parallel communication and comes with ST7290 LCD controller/driver IC. Interface communication mode can be switched between parallel and serial using PSB PIN 15. This graphical LCD has an automatic power on Reset function and can be easily controlled by MCU such as 8051, AVR, ARM, Arduino and Raspberry Pi.

As used in various electronic projects, generally we use Arduino to interface our Graphical LCD. When you are using a Graphical LCD with Arduino, I advise you to use it in serial mode, which will decrease the use of no. of pins. The below circuit diagram will help you to connect your Graphical LCD with Arduino in serial mode.
