Description

Done with tedious mono color backlight? This Grove enables you to set the color to whatever you like via the simple and concise Grove interface. It takes I2C as communication method with your microcontroller. So number of pins required for data exchange and backlight control shrinks from ~10 to 2, relieving IOs for other challenging tasks. 


Besides, Grove - LCD RGB Backlight supports user-defined characters. Want to get a love heart or some other foreign characters? Just take advantage of this feature and design it!


This product is a replacement of Grove - Serial LCD. If you are looking for primitive 16x2 LCD modules, we have green yellow backlight version and blue backlight version on sale also.


Features

  • Colorful RGB Backlight

  • Built-in English and Japanese fonts

  • I2C communication, uses only two IOs

The contrast is very poor on mine. I can barely read the text. It is plugged into a Wio Link, and has 2.5a of power. Can I adjust the contrast?

I had the same problem. The backlight was fine, but the contrast was so poor that I could only ready the characters if I tilted the display just right. What I determined was that the voltage being supplied to the display was too low. I was powering the display from a Nano, and powering the Nano off of USB. When I read the voltage going to the display on the 5V pin, it was only about 4.3V. When I powered the Nano via the VIN pin and thus it was able to put a full 5V out of the 5V pin, the display worked just fine.

Yes, This Grove need 5V, but the wio link/node just provide 3V. Thanks god you can see on 3V3.You need some hack for this, look this thread: http://www.seeed.cc/Grove-LCD-RGB-Backlight%3A-no-output-t-11260.html

Is there a schematic for this anywhere? I'm trying to use it with a Grove Shield on an ST Micro Nucleo board. I've got it hooked up to my scope and am watching the i2c bus. One of the questions is the address for the LCD and RGB driver are shifted in t

Replying to my own post but I solved my issue. To use this display with the ST Micro Cortex M series you set the GPIO's to Open Drain, and tie them through 10K pull up resistors to 5V. Then the display will respond correctly (the ST inputs are 5v toler
