Good value, quality could be better
These work well and are as described. Contrast had to be adjusted via the trimpot at the back. The backlight is bright. There doesn't seem to be any way to control brightness in software, can just turn it on or off. The backlight is required though. Nothing is visible without it. Both units worked fine. Quality could have been better with a little attention to how these are assembled. Looks like they were put together in a hurry.

5.0 out of 5 stars Easy to get going
Reviewed in the United States on June 11, 2020
No documentation, but it's a 1602 with the PCF8574 chip on the backpack. This is a really commonly used setup and there are plenty of libraries for it. Other than power, just 2 wires are needed to get it setup for I2C. My address was 27 and had the yellow tape on the USB port.

If your screen is blank or not working but the LED light is on, make sure you adjust the contrast (both of mine came adjusted all the way down). This is done by adjusting the potentiometer, which is a blue box on the back of the LCD with a screw in it. Use a screw driver to slowly turn the screw until you can see the individual numbers/letters.
