STEVAL-ILL062V1

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 For further information contact your local STMicroelectronics sales office. 1/5 www.st.com Schematic diagrams 1 STEVAL-ILL062V1 Schematic diagrams Figure 1.
