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.
Features
Four LED1202 devices driving up to 48 LEDsOne double row pin array connector for external LED panel connectionOne jumper selector for internal/external LED power supplyOne panel with 48 white LEDs/16 RGB LEDs includedArduino UNO R3 connectorsFree comprehensive development firmware library compatible with STM32CubeScalable solution for multiple board stackRoHS and WEEE compliant
Typical applications
- Home, building and city automation
