16×2 20×4 I2C LCD Display

The LCDs are designed with an industry-standard HD44780 equivalent LCD controller.

The module provides a simple and cost-effective solution for adding a character display to your project. It offers a very clear and high-contrast white text upon a blue background/backlight.

This display overcomes the drawback of a Parallel LCD Display in which you’ll waste about 8 Pins on your MCU for the display to get working. Luckily in this product, an I2C adapter is directly soldered right onto the pins of the display. So all you need to connect are the I2C pins, which show a good library and little coding.

The I2C is a type of serial bus developed by Philips, which uses two bidirectional lines, called SDA (Serial Data Line) and SCL (Serial Clock Line). Both must be connected via pulled-up resistors. The usage voltages are standard as 5V and 3.3V. The values shown on the display can be either simple text or numerical values read by the sensors, such as temperature or pressure, or even the number of cycles that the MCU is performing.
