16-Channel 12-bit PWM / Servo Driver Module – I2C PCA9685 for Arduino & Raspberry Pi
The 16-Channel 12-bit PWM/Servo Driver based on PCA9685 is an ideal solution when your microcontroller runs out of PWM pins. Using just two I2C pins, this module can independently control up to 16 PWM outputs, making it perfect for robotics, LED dimming, and multi-servo projects.The PCA9685 features a built-in oscillator and clock, allowing it to run completely free-standing without constant updates from the microcontroller. With 6 address select pins, you can daisy-chain up to 62 boards on a single I2C bus, giving you control over an incredible 992 PWM channels.
Features
- 16 independent PWM channels controlled via I2C interface
- 12-bit resolution (4096 steps) per channel
