PCA9685 16-Channel PWM Controller with I2C Interface

Overview:

The PCA9685 is a versatile 16-channel PWM controller with an I2C interface, perfect for projects requiring multiple PWM outputs such as robotics, lighting, and motor control. It allows you to control up to 16 independent channels with 12-bit resolution (4096 steps), offering smooth and precise signal control. Designed for easy integration with Arduino, Raspberry Pi, and other microcontrollers, the module supports daisy-chaining to expand beyond 16 channels. It also includes features like adjustable frequency (up to ~1.6 kHz), a built-in oscillator, and low standby current, making it an efficient and reliable choice for hobbyists, makers, and engineers.
