PCA9685 16 Channel PWM Servo Driver Module

The PCA9685 16 Channel PWM Servo Driver Module is a compact, easy-to-use expansion board that gives your microcontroller precise, low-latency control of up to 16 servos or LEDs — ideal for robotics, animatronics and smart lighting projects.

• Key features & benefits: 16 independent PWM channels with 12-bit (4096-step) resolution deliver smooth, jitter-free servo motion and fine LED dimming control; adjustable PWM frequency (approx. 24 Hz—1.6 kHz) lets you optimise performance for servos or lighting; I²C interface uses only two MCU pins, freeing your CPU for higher-level tasks.
• Power & scalability: 5V-compliant logic (2.3V—5.5V supply range) and a separate V+ terminal for external servo power protect your controller and support high-current servos; chain up to 62 modules on one I²C bus for massive expansion.
• Easy integration: Standard 3-pin servo connectors, address jumpers, and output-enable make the board simple to wire into Arduino, Raspberry Pi, ESP32 and other platforms.

Use cases include multi-servo robot arms, remote-control models, automated camera rigs, LED matrices and stage lighting where precise PWM and scalable channels matter. The module's on-board clock means once configured it runs independently, reducing MCU load and simplifying code.
