IIC/I2C + LCD Board 2004 20X4 5V Blue

As we all know, LCD and LED segment display had greatly enriched human-computer interactions. But a connection with any controller usually requires numerous IO port lines, which is not only a big problem for controllers with limited peripheral interfaces but also poses restrictions on other functions the controller has. In order to solve this problem, we develop LCD2004 Module. This module carries I2C interface and is easy to use.
