Description
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.
