Product overview
Description
The X-NUCLEO-LED12A1 LED driver expansion board for STM32 Nucleo features four LED1202 devices that can drive up to 48 LEDs.
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 analog and 12-bit digital dimming control.
The X-NUCLEO-LED12A1 expansion board comes with an additional LED panel board that houses two LEDs matrices: a 6x8 white LED matrix and a 4x4 RGB matrix.
LED matrices can be supplied via an external power supply connected to J13 connector and by selecting the right path through J15 jumper to reach the maximum luminosity available.
