PCA9685 16-Channel PWM/Servo I2C Driver Module
The PCA9685 16-Channel PWM/Servo Driver Module is a powerful I2C-based controller designed to drive up to 16 servo motors, LEDs, or other PWM-controlled devices using only two communication pins (SDA & SCL). Featuring 12-bit PWM resolution (4096 steps), it delivers smooth and precise control while reducing the processing load on your microcontroller. Ideal for Arduino, Raspberry Pi, ESP32, STM32, and other development platforms, this module is perfect for robotics, automation, animatronics, RC projects, and LED lighting systems.
