NXP Semiconductors OMPCA9959LEDEV Evaluation Board

NXP Semiconductors OMPCA9959LEDEV Evaluation Board is designed to evaluate the PCA9959 LED lighting driver. This board features LEDs for color mixing, blinking, and dimming demonstrations. The graphical interface helps to explore the different functions of the driver. The OMPCA9959LEDEV evaluation board can be connected in series with other SPI-bus demo boards to create an evaluation system. Typical applications include Red/Green/Blue/Amber (RGBA) LED drivers, LED displays, LCD backlights, and keypad backlights for cellular phones.
