LED Matrix is low cost and usually used to display simple numbers and images. The Grove - LED Matrix Driver is the I2C based product which allows you to control the LED matrix with our prepared and easy-to-use libraries, or you can create your own library to control it to satisfy your need. The 8*8 LED Matrix can be assembled and unassembled from the driver board easily, so it is convenient to change different color LED matrix display based on your need.
