PCA9685 16-Channel 12-bit PWM Servo Motor Driver

Description

The PCA9685 16-Channel 12-bit PWM Servo Motor Driver is a powerful I2C-controlled module designed for controlling up to 16 servos or LEDs with high precision. It is ideal for robotics, RC projects, automation, and Arduino-based control systems . This module uses the PCA9685 PWM driver chip from NXP, which provides 12-bit resolution (4096 steps) per channel. In addition, it operates via the I2C interface , allowing control using only two pins from your microcontroller. Because it supports daisy-chaining , multiple boards can be connected together to control up to 992 servos from a single I2C bus. Also, it works perfectly with Arduino, Raspberry Pi, STM32, and ESP32 , therefore it’s ideal for advanced servo or LED control projects. Key Features: IC: PCA9685 16-channel PWM driver Resolution: 12-bit (4096 steps per output) Communication: I2C interface (address configurable) Operating Voltage: 5V (logic 3.3V compatible) Controls up to 16 servos or LEDs simultaneously Frequency range: 40Hz–1000Hz Supports daisy-chain connection for up to 62 modules Compatible with Arduino, Raspberry Pi, ESP32, and STM32 Ideal for robotics, lighting control, and automation projects Perfect for students, hobbyists, and engineers, the PCA9685 16-Channel PWM Driver is the ideal choice for smooth, accurate, and efficient multi-servo control using Arduino or Raspberry Pi.
