Add 4x20 Grove LCD
The 2x16 Grove LCD is terrific, especially with the backlight color changes. Bring out a 4x20 version.
By the way, what are the hidden I2C addresses on this device? They should be documented so multiple devices can be used.

Thanks for adding this new idea and we will review it.
The I2C address for Grove RGB LCD Backlight is fixed by hardware. If you would like to have multiple devices running on Arduino at the same time, you can check this Soft_I2C library: https://github.com/loovee/Arduino_SoftI2C .
