Mikroe LED Driver 12 Click

Mikroe LED Driver 12 Click features the NXP Semiconductors PCA9532 16-bit I²C-configurable I/O expander optimized for dimming LEDs. The PCA9532 offers high efficiency, supporting up to 16 LED channels. It delivers 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. Any bits not used for controlling the LEDs can be used for GPIO expansion, which provides a simple solution when additional I/O is needed for some sensors, push-buttons, or alarm monitoring.
