This RGB soft screen is composed of 7x71 RGB lights. It communicates with the main control through the serial port to display strings and change the font and background color. You can set the display brightness and moving speed, modify and display the contents of the message list.
- Feature
- Support soft and hard serial communication, baud rate 19200

SKU: DFR0597
This is a library for the Arduino IDE, which can help Arduino to communicate with 7x71 Flexible RGB LED Matrix.
The library makes it easy to configure the sensor via Serial
To use this library, first download the library file, paste it into the \Arduino\libraries directory, then open the examples folder and run the demo in the folder.
