DFRobot I2C Backlight Display Module for Arduino (Black Text)
Offers a 16x2 RGB LCD screen
Supports both backlit brightness and color adjustment
Backlit: RGB adjustable backlit (16 million)
Communication: I2C
Operating Voltage: 3.3 V ~ 5.0 V
The DFRobot LCD Keypad Shield V2 for Arduino offers a 16×2 RGB LCD screen.
The RGB LCD shield supports both backlit brightness and color adjustment. It offers 16 million color combinations that make colors on-screen appear vivid and bright.
Moreover, the screen backlit color can be programmed to adjust automatically according to the changes in the measured parameters, which allows you to intuitively feel the real-time status of the monitored object. For example, when detecting the indoor temperature, set the backlit color to blue if the temperature is ≤26 °C and change the color to red if the temperature is >26 °C.
The RGB LCD shield extends all IOs of Arduino UNO on the back, by which you can connect with modules like sensors, LEDs, and servos while using this screen to display content. More possibilities for your creative projects！
Works fine but LCD pinouts selected have limitations
The hardware is good quality with nice long and wide pushbuttons. Simple test program would not compile - mostly errors in text wraparound. Hardware works fine with Arduino UNO. Review pinouts for your particular application to make sure there are no conflicts with assigned LCD digital pins. For example, Arduino Uno pins D9 and D10 are used for Timer 1 outputs. It would have been better for my application to assign the LCD pins used by UNO pins D9 and D10 to UNO pins D11 and D12 instead if you need to use Arduino UNO Timer 1 based outputs.

Easy to use, good visibility
The DFRobot LCD Keypad shield came promptly, and was well packaged. Simple to use. Uses Arduino digital pins 4-10 to drive it, and pin A0 handles all 5 pushbuttons with different analog voltage values. Uses the Arduino liquid crystal library, which I found was already installed in my IDE. Coding is relatively simple, e.g. lcd.setCursor(0,0); lcd.print("Push the buttons"); sends the message to the screen, which is nice and bright. You can write variable values on one part of the screen, and leave the unchanging text on another part of the screen without the need to re-write the unchanging text. Nice!

Nice shield. Easy to Use.
I like these sheilds and have used a number of the first ones (SKU:DFR0009) for various products. The buttons are nice and reliable, and the reset is kept short so that it doesn't ned to stick through the surface of the enclosure. Nice feature The V2 of the board is just as sweet, but now separates the four navigtion buttons (UP, DOWN, LEFT, RIGHT) from the SELECT button so that it is easier to use by feel, which is a nice feature. The long buttons stick well above the surface of the LCD so thay don't need separate button caps which is great.
