PCA9685 Servo Driver

The PCA9685 16-Channel 12-bit PWM/Servo Driver is a compact I2C-bus controlled module designed to drive up to 16 servos or LEDs independently. It offloads the PWM generation from your microcontroller (like Arduino or Raspberry Pi), freeing up processing power and GPIO pins. With a 12-bit resolution (4096 steps), it offers precise duty cycle control, making it ideal for smooth servo movements and accurate LED dimming. The module operates with a supply voltage range of 2.3V to 5.5V, with inputs and outputs tolerant up to 5.5V. It features an adjustable PWM frequency up to 1.6 KHz and supports daisy-chaining for controlling even more channels. This driver is essential for complex robotics, animatronics, and lighting projects requiring synchronized multi-channel control.
