Grove - LED Matrix Driver v1.0 is UART (Serial) to dot matrix LED driver that incorporates various graphics functions.It can only support 32×64 LED matrix. This product is Grove compatible UART interface. It provides easy and rich APIs that abstract the complexity of the underlying LED driving hardware. All you need to is just call these APIs in code to implement different functionalities for your project.
Each dot(i.e pixel) support dual color LEDs. It can produce three colors totally: red (primary color), green(primary color) and yellow (mixed color). The input current for all LEDs can be set at a time.
Note: This Grove module does not support changing the input current of each LED separately.
