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 cost-effective monochrome backlight serial for you:
Colorful RGB Backlight
Built-in English and Japanese fonts
I2C communication, uses only two IOs
Automatic power-on reset
For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your using of the product.

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 tQuestion by: admin on 2018-12-18 02:34:08
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 tolerAnswer by: admin on 2018-12-18 02:34:08
The Wio Link API says that "you must jump VCC of Grove-LCD to 5V". How can I do this without backfeeding 5V into the Wio Link and frying it?Question by: admin on 2018-12-18 02:32:02

Hi Andrew, Please take a picture of hardware setup and provide the code as well, drop mail to firstname.lastname@example.org. We will simulate the issue. thanks.Answer by: admin on 2018-12-18 02:23:45
Is there a data sheet for this device? Or is the source for the Arduino library available somewhere?Question by: admin on 2018-12-18 02:23:39
Hi there, please refer to wiki, **http://wiki.seeedstudio.com/Grove-LCD_RGB_Backlight/**, includes the library. thanks.Answer by: admin on 2018-12-18 02:23:39

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?Question by: admin on 2018-12-18 02:19:51
I've found that contrast is low when powering from a 5V USB port off a computer. I hooked up a 12V 5A power supply to the 2.1mm barrel connector on a Mega Arduino, and wow - contrast is great! Yes, normally you probably don't need (or want) a 12V 5A power supply, but in my case I use it to power the Mega and a 5m (16.4 ft) RGB LED strip - which takes a far amount of amperage to drive the LEDs anyway. Give it more power and you will likely see improved contrast. I have a ton of other stuff attached to the Mega, and its all working well with the 12V 5A power supply...Answer by: admin on 2018-12-18 02:19:51
