STMicroelectronics LED Driver for LED1642GW for STM32 Nucleo

The X-NUCLEO-LED16A1 is an STM32 Nucleo expansion board designed to provide an evaluation platform for the LED1642GW 16-channel LED driver device. Multiple drivers can also be cascaded by coupling X-NUCLEO-LED16A1 expansion boards. RGB or single colour LEDs can be connected to the board. Separate brightness control is possible for each channel.
