The PCA9685 16-channel PWM driver module is an I2C-controlled board designed to simplify servo and LED control. It features 12-bit resolution PWM for precise positioning and adjustable frequency up to 1.6 kHz. The module is compatible with both 5V and 3.3V logic, supports cascading multiple boards, and includes built-in protections such as reverse polarity and output series resistors. It is ideal for driving multiple servo motors in robotics, automation projects, and LED dimming applications, allowing the microcontroller to offload continuous PWM generation tasks.
