16-Channel 12-bit PWM Servo Driver Shield – PCA9685 I2C Module
The 16 Channel 12-bit PWM Servo Drive Shield Board (PCA9685) for Arduino is a specialized module designed to control multiple servo motors and other devices requiring PWM (Pulse Width Modulation) signals. It features the PCA9685 chip, which is an I2C-controlled PWM driver capable of driving up to 16 servos simultaneously. This shield is highly useful for projects that require precise control of multiple servos, such as robotic arms, model vehicles, or automated systems. Powerful 16-channel PWM driver shield using PCA9685 over I2C interface, capable of controlling servos, LEDs, motors, and more. Delivers 12-bit resolution (4096 steps) and supports multiple modules on the same bus—perfect for robotics, animatronics, and automation projects with Arduino or Raspberry Pi.
