Grove - LCD RGB Backlight is a full-color backlight 16x2 LCD. High contrast and ease of use make it a perfect I2C LCD display for Arduino and Raspberry Pi.
The traditional 1602 LCD requires up to 10 I/O pins to display, and the 1602 LCD with RGB backlight requires an extra 3 pins to control the backlight color. This will take up a lot of I/O pins on the main control board, especially for development boards with less I/O resources such as Arduino and Raspberry Pi. Grove - LCD RGB Backlight makes it totally different! With the help of Grove I2C connector, only 2 signal pins and 2 power pins are needed. You don't even need to care about how to connect these pins. Just plug it into the I2C interface on Seeeduino or Arduino/Raspberry Pi+baseshield via the Grove cable. No complicated wiring, no soldering, no need to worry about burning the LCD caused by the wrong current limiting resistor. Easy peasy.
What's more, this LCD module is not only a character LCD but also can display your DIY images, such as a heart and a smiling face. 16x2 means two lines and each line have 16 columns, 32 characters in total. Each character contains 5*8 pixels. You can check here to make your own images array, just release your creativity and imaginations.
As the name RGB backlight indicates, you can set any color you like to be the backlight. You can also have the backlight change with the program, such as using a green backlight when displaying a smile, and turning the backlight to red when the angry face appears. Well, if you don't need a colorful backlight, you can choose our monochrome LCD series. They also use the easy-to-use Grove I2C interface and are more cost effective.

Grove - LCD RGB Backlight
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 a
No character color It would be nice if the character text has color too.
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
