Arduino LCD 12864 Shield Is Compatible With Serial Interface And Parallel Interface

Description :

Arduino LCD 12864 Shield is compatible with both serial interface and parallel interface.

This item has the both serial interface and parallel interface、the backlight control switch (compatible with serial and parallel mode)、ontrast adjustment knob、insert IDC6 socket and IDC14 socket, and can connect with Arduino Sensor Shield through the special cable which come with this item.

According to the example code we provide, you can use the Arduino as MCU to complete the function of displaying 128 characters (8 X16 dot matrix) and graphic display (128 X64 dot matrix), best choice for Arduino interactive display.
