نظرة عامة على المنتج
The PCA9685PW is an NXP 16-channel, 12-bit PWM Fm+ I2C-bus LED controller. Each channel has 12-bit resolution (4096 steps) for duty cycle control, making it ideal for LED dimming, servo motor control, and RGB color mixing applications. The device operates from 2.3V to 5.5V and supports I2C fast-mode plus at 1MHz.
