This LCD works well with Arduino-based projects and is compatible with the ArduinoMenu library, or standalone. The product is easy to integrate and is stylish / unconventional because of color. The high-contrast of the letter pels against the blue background is easy to read. Great value for the price.

The only thing I can say is that they only gave me enough wires to hook up two of them instead of all three. It was no big deal though. I just generated a four conductor ribbon cable and connected it to the custom printed circuit boards and they went. The screens performed perfectly. I have six of them operating in a clients machines right now. He’s very happy with them, I am very happy with them.

The product is and works mostly as advertised. Unfortunately, the potentiometer does not control the backlight brightness; it controls the contrast of the characters, which makes it useless. I was not able to find a way to control the backlight brightness, and the display is mostly illegible without some backlight.

I bought one set of three while only needing two. The first one I wired up I used the default address (0x27). It worked fine. The second one I used I changed its address to 0x26. It did not display anything. So I went to my third unit also changing its address to 0x26. It work fine. Two working out of three isn’t bad but not great either

These screens are great for simple headless projeects. They are extremely easy to use. Just make sure you enable the I2C bus and appropriate drivers smbus or smbus2 will be required. It is amazing value
