Mikroe LED Driver 8 Click

Mikroe LED Driver 8 Click is used for dimming and blinking 32mA RGBA LEDs. The board features the NXP Semiconductors PCA9957HNMP 24-channel SPI-compatible constant current LED driver. It has 24 LED output channels with a programmable group dimming/blinking mixed with individual LED brightness. Programmable LED output delay reduces EMI and surge currents. It also possesses gradation control for all channels where all 24 constant current output channels can sink up to 32mA, and tolerate up to 5.5V in its OFF state.
