16‑Channel 12‑Bit PWM/Servo Driver Module – I²C Interface, PCA9685, 3.3V/5V Compatible

This 16-Channel 12-Bit PWM/Servo Driver Module is built around the PCA9685 controller, offering precise PWM signal control for up to 16 outputs using just two I²C pins. It's an ideal choice for robotics, motor control, lighting systems, and general-purpose servo control. The onboard PWM driver supports 12-bit resolution (4096 steps) per channel, allowing fine-grained signal generation. It supports both 3.3 V and 5 V logic, making it compatible with a wide range of microcontrollers including Arduino, Raspberry Pi, ESP32, and STM32. It also includes external power input for servos, enabling control of high-power actuators without overloading your MCU. Multiple modules can be chained together via addressable I²C addressing, expanding your output capability for more complex projects.

Key Features:

• Based on PCA9685 controller – 16 independent 12-bit PWM outputs
• I²C controlled – requires only 2 GPIO pins from your MCU
• 3.3 V/5 V logic compatible – works with Arduino, Raspberry Pi, etc.
• Integrated clock – no continuous signal refresh needed
• External power terminal for driving servos (up to 6 V)
• I²C address selectable – up to 62 modules on the same bus
