I2C Backpack Make your LCD easier to use

Although all LCDs are basically the same, this model comes with an I2C backpack, making it very easy to use is. Rather than requiring 4 serial lines (pins) plus power and a contrast potentiometer, the backpack offers communication over a 2-wire I2C connection and has a built-in contrast potentiometer.

Pros

Fully Assembled and Tested 20x4 Serial LCD Module

Cons

So far so good
