Description
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.
