    The X-NUCLEO-LED16A1 is an STM32 Nucleo expansion board designed to provide an application for the 16 channel LED driver LED1642GW. Multiple drivers can also be cascaded by coupling X-NUCLEO-LED16A1 expansion boards.


    Depending upon the end application, RGB or single color LEDs can be connected to the board. Separate brightness control is possible for each channel.


    It is compatible with the STM32 Nucleo board family and equipped the Arduino™ UNO R3 connector layout.
