The STMicroelectronics X-NUCLEO-LED12A1 LED driver expansion board for STM32 Nucleo features four LED1202 devices. The LED1202 is a 12-channel low quiescent current LED driver, which guarantees 5 V output driving capability. Each channel is able to provide up to 20 mA with a headroom voltage of 350 mV (typ.) only. The output current can be adjusted separately for each channel through an 8-bit analogue and 12-bit digital dimming control. The X-NUCLEO-LED12A1 expansion board comes with an additional LED panel board that houses two LEDs matrices 6x8 white LED matrix and a 4x4 RGB matrix. Four LED1202 devices driving up to 48 LEDs
