However, with this I2C or SPI interface LCD module, you will be able to realize data display via only 2 or 3 wires,while still making it easy to interface with the LCD. And this LCD module actually cost no more resources at all. It is fantastic for based project; This board have IIC and SPI connector, can be completely compatible with 2004 LCD; Slide switch to control different communication mode. Interface: I2C or SPI; Supply voltage: 5; Work with 4 line 20 character LCD; Come with IIC/SPI interface, which can be connected by IIC/SPI dedicated cable; IIC default address: 0x20; If address is repeat or you want to change, you can weired A0 A1 A2 to high or low level.
