Grove - Red LED Matrix w/Driver is based on HT16K33. It is the combination of the 20mm 8 x 8 square LED Matrix - Red and the Grove - LED Matrix Driver and usually used to display simple numbers and images.

LED Matrix is low cost and usually used to display simple numbers and images. Grove - Red LED Matrix w/Driver is the combination of the 20mm 8 x 8 square LED Matrix - Red and the Grove - LED Matrix Driver. The HT16K33 is a memory mapping and multi-function LED controller driver 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 software configuration features of the HT16K33 makes it suitable for multiple LED applications including LED modules and display subsystems. The HT16K33 is compatible with most microcontrollers and communicates via a two-line bidirectional I2C-bus.
