Description
Product Overview
Elevate your robotics and automation projects with the 16‑Channel PWM Servo Drive Board, engineered around the versatile PCA9685 I²C interface. Designed for seamless integration with Raspberry Pi and other microcontrollers, this module delivers precise, high‑resolution control for up to 16 hobby servos or stepper motors, making it the ideal choice for drones, RC cars, robotic arms, and home‑automation systems.
Key Features
- 16 independent PWM channels with 12‑bit resolution (0.1° precision)
- Low‑power I²C communication – 400 kHz fast‑mode support
- Adjustable frequency range 24 Hz – 1526 Hz (default 50 Hz for standard servos)
- Built‑in voltage regulator (5 V) and level‑shifting for 3.3 V/5 V logic compatibility
- Compact 3.5 × 3.5 cm PCB, perfect for breadboard or custom PCB designs
- Robust 1 A current limit per channel – safe for high‑torque servos
- Easy-to-use Python library with pre‑loaded examples (Raspberry Pi, Arduino, ESP32)
- Open‑source firmware and schematic available for advanced users
