This LED Matrix combines an 8 x 8 red LED matrix with the Grove LED Matrix Driver. The driver uses the HT16K33, a memory-mapped, multifunctional LED controller that allows easy matrix control through provided libraries or custom libraries. The HT16K33’s software configuration suits various LED projects, such as modules and display systems. It communicates with most microcontrollers via a two-line I2C bus. If you're looking for a matrix with multiple colours, click here to find it in our shop.
