PCA9959HN-ARD is a LED driver Arduino® shield evaluation board. The PCA9959HN-ARD Arduino shield allows easy integration with Arduino EVKs to evaluate the LED controller features for color mixing, blinking and dimming LEDs. A graphical interface allows the user to easily explore the different functions of the driver to create an evaluation system. Each LED output has its own 6bit resolution (64steps) preset current configuration, with an absolution accuracy of ±8%. Typical applications are industrial, keypad backlights, LED displays, RGB or RGBA LED drivers, smart assistance response LED lighting.
