16-Channel 12-bit PWM/Servo Driver I2C interface PCA9685 for Arduino Raspberry Pi
The PCA9685 16-Channel PWM/Servo Driver is a powerful, I2C-controlled PWM expansion board that allows you to control up to 16 independent PWM signals using just two I2C pins. Designed around the NXP PCA9685 chip, this module is ideal for driving servos, LEDs, and other PWM-controlled devices with high precision and minimal pin usage on your microcontroller.
With 12-bit resolution (4096 steps) per channel and the ability to chain multiple boards (up to 62 on a single I2C bus), it’s a perfect solution for advanced robotics, animatronics, LED lighting, and mechatronic projects.
