STMicroelectronics X-NUCLEO-LED12A1 LED Driver Expansion Board

STMicroelectronics X-NUCLEO-LED12A1 LED Driver Expansion Board is for STM32 Nucleo and features four LED1202 devices that can drive up to 48 LEDs. The LED1202 is a 12-channel low quiescent current LED driver, which guarantees 5V output driving capability. Each channel is able to provide up to 20mA with a headroom voltage of 350mV (typ.) only.

The output current can be adjusted separately for each channel through an 8-bit analog and 12-bit digital dimming control. The STMicroelectronics X-NUCLEO-LED12A1 expansion board comes with an additional LED panel board that houses two LEDs matrices: a 6×8 white LED matrix and a 4×4 RGB matrix. LED matrices can be supplied via an external power supply connected to the J13 connector and by selecting the right path through the J15 jumper to reach the maximum luminosity available.
