STEVAL-LLL001V1:STLED524 evaluation kit (5 x 24 matrix LED display driver)

The STEVAL-LLL001V1 board is designed to demonstrate the features of the STLED524 intelligent matrix LED display driver with a 5 x 24 matrix of SMD white LEDs incorporated on the board.

Two boards can also be joined using the on-board connectors to drive a 10 x 24 LED matrix.

The board is driven by the USB control board for interface with the graphical user interface (GUI), but there is also an SPI interface connector on the STEVAL-LLL001V1 which can be used for customized control.
