STEVAL-ILL062V1 High brightness LED array driver based on the STP16CPC26 Data brief Description The STEVAL-ILL062V1 evaluation board is a high brightness LED array driver application based on the 16 channel, constant current LED sink driver STP16CPC26 from STMicroelectronics. The LED driver is configured and controlled through an 8-bit STM8S microcontroller via SPI interface. The industrial-grade L7981D DC-DC converter provides the voltages and power for the overall functioning of the board. Features Demonstrates pre-configured patterns (with adjustable brightness/speed) such as rolling text, wave effect, dot sequence, etc. LED test points Potentiometer to change brightness and speed of patterns SWIM connector to program microcontroller Push buttons (backward/forward) to change between modes DC supply connector: 6 V - 24 V 32 white LEDs RoHS compliant August 2014 DocID025914 Rev 1 1/5 For further information contact your local STMicroelectronics sales office. www.st.comSchematic diagrams STEVAL-ILL062V1 1 Schematic diagrams Figure 1.
