Feature
●The LCD display was always a window device in interaction with humans and computers. For example, some instrument device prompt window, temperature and humidity prompt box, device running status monitor, counting device prompt screen all have LCD shapes
●Common LCD1602, LCD2004, and LCD12864 are manufactured with LCD material and communicated using I2C bus
●High performance serial bus with bus rules and fast and slow device syncing required for multi-master systems. The I2C bus only has two two-way signal lines of the Serial Data Line (SDA) and Serial Clock Line (SCL)
●Compatible with all devices with I2C interface such as Arduino, raspberry pi, beagle bone black, tinker board, stm32, esp32
