Works well with Arduino Nano

The display was easy to integrate and use in my Arduino project. It would have been nice to have a Stemma port on the PCB.

Ok, so I won't go into how to enable I2C as it varies per computer, but search that first. You can verify if connected via i2cdetect linux command. I'm using smbus2 python library.NOW BIG ADVICE:-make sure the screen is plugged into 5V as they say in product description or text will be very very hard to see-adjust the contrast screw (in the blue thing) if you don't see any text or just see black bars.

They work as advertised, and it is very easy to find a tutorial online for driving them. will be purchasing more in the future

I tried several different Arduino LCD i2c libraries, and none seemed to work. I was about to return the displays but noticed a potentiometer on the i2c interface. Little did I know that this controls screen contrast. It really would have been helpful to have a note somewhere explaining this.The units were shipped with the contrast set, so the characters were not visible. No one tested these units before they left the factory.

I was upgrading an Arduino project by replacing a 2x16 display with this 4x20 display. The legacy display didn't have the I2C interface & I initially thought I'd need to unsolder that little interface board for it work similarly. However a couple YouTube scans explained the I2C environment & how easy it is to hang multiple devices on the buss. In short, it works great with just 4 wires, including power.

DOA. Unfortunately I had to send this screen back. The backlight worked, but the LCD 4x20 Characters did not. I purchased another and worked just fine. It was a replacement screen for a project. I had verified the drivers I was running were correct before sending back. As well as tried adjusting the potentiometer for screen brightness. I gave 3 stars for DOA(Dead on Arrival).

Just received the LCD and connected it to an Arduino to test it. It works as expected. The I2C comm saves some pins on the Arduino, which is nice. I like having the jumper on the backpack for the LED back-light. I connected the upper pin, labeled "LED" to a PWM pin on the Arduino. This allowed me to dim the back-light using the analogWrite() command.
