The MikroElektronika LED Driver 12 Click is a compact add on board that simplifies the control of multiple LEDs. This board features the PCA9532 which is a 16 bit I2C configurable I/O expander optimized for dimming LEDs in 256 discrete Red or Green or Blue steps from NXP Semiconductors. The PCA9532 offers high efficiency, supporting up to 16 LED channels and delivering a maximum of up to 25mA of LED current per channel. It contains an internal oscillator with two user programmable blink rates and duty cycles coupled to the output PWM. This Click board is suitable for colour mixing and backlight application for amusement products, LED status signalization, home automation projects and many more.
