NXP Semiconductors PCA9955BTW-ARD LED Driver Arduino Shield

NXP Semiconductors PCA9955BTW-ARD LED Driver Arduino Shield allows easy integration with Arduino EVKs to evaluate the LED controller features for color mixing, blinking, and dimming LEDs. This LED driver Arduino Shield features programmable hold-on time after ramp-up, and hold-off time programmable brightness current output adjustment. The PCA9955BTW-ARD driver support up to four groups of LED gradation control and each LED channel is assigned to one of four groups. This LED driver Arduino Shield operates at 3V to 5.5V supply voltage and 170µA low standby current. The PCA9955BTW-ARD driver is used in keypad backlights, LED displays, RGB or RGBA LED drivers, and smart assistance response LED lighting.
