Excellent unit, works perfectly

There are complaints that this unit does not show anything on the display. Because the user is not aware that the output brightness has to be adjusted via the potentiometer screw on the back of the device. When trying to use the display for the first time, customize the display to your liking. Nothing showed up on my first try until the brightness control was changed.

Pros
  • Electronics
Cons
  • Compatibility

I2C backpack makes LCD easier to use

Although all LCDs are basically the same, this model is matched to I2C backpack, which makes it very easy to use. 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
  • LCD
Cons
  • Weight
