1-10PCS PCA9685 Robot Controller IIC Interface 16 Channel 12-Bit PWM Servo Motor Driver Board – the ultimate solution for controlling multiple servo motors with precision and ease on Arduino and Raspberry Pi projects. This compact, high‑performance board expands your robot’s capabilities, allowing you to manage up to 16 servos or motors from a single I2C address.
Key Highlights
- 16‑channel, 12‑bit PWM output – delivers smooth, high‑resolution servo control.
- Built on the industry‑standard PCA9685 chip – reliable and widely supported.
- Compatible with Arduino, Raspberry Pi, ESP32, and other I2C‑capable microcontrollers.
- Wide input voltage range (3.3V–5V) – works with most hobbyist boards.
- Low‑power design – ideal for battery‑powered robots and drones.
- Easy to wire: 5V, GND, SDA, SCL, and 16 PWM outputs.
- Pre‑calibrated PWM frequency (default 50Hz) – perfect for hobby servos.
- Stackable I2C addresses – use multiple boards without conflict.
- Compact footprint – fits in tight robot chassis or embedded systems.
- Robust, industrial‑grade components for long‑term reliability.
Why Choose This Servo Driver Board?
Whether you’re building a line‑following robot, a robotic arm, or a multi‑axis camera gimbal, this board gives you the precision and scalability you need. The 12‑bit PWM resolution ensures smooth motion, while the I2C interface keeps your wiring simple and clean. With support for up to 16 channels, you can control dozens of servos from a single microcontroller, freeing up valuable pins for sensors and other peripherals.
Quick Start Guide
- Connect 5V and GND to your power supply.
- Wire SDA and SCL to your microcontroller’s I2C pins.
- Use the Adafruit PCA9685 library or equivalent to initialize the board.
