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.
