STEVAL-ILL062V1High brightness LED array driver based on the STP16CPC26Data briefDescriptionThe STEVAL-ILL062V1 evaluation board is a highbrightness LED array driver application based onthe 16 channel, constant current LED sink driverSTP16CPC26 from STMicroelectronics.The LED driver is configured and controlledthrough an 8-bit STM8S microcontroller via SPIinterface.The industrial-grade L7981D DC-DC converterprovides the voltages and power for the overallfunctioning of the board.Features Demonstrates pre-configured patterns (withadjustable brightness/speed) such as rollingtext, wave effect, dot sequence, etc. LED test points Potentiometer to change brightness and speedof patterns SWIM connector to program microcontroller Push buttons (backward/forward) to changebetween modes DC supply connector: 6 V - 24 V 32 white LEDs RoHS compliantAugust 2014DocID025914 Rev 1For further information contact your local STMicroelectronics sales office.1/5www.st.com
