STEVAL-LLL001V1

The STEVAL-LLL001V1 from STMicroelectronics is STLED524 evaluation kit with 5 x 24 matrix LED display driver incorporated on the board. This board is designed to demonstrate the features of the STLED524 intelligent matrix LED display driver. 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. Two boards can also be joined using the on-board connectors to drive a 10 x 24 LED matrix.
