Featuring 12-bit resolution (4096 steps) and I2C communication, this module frees up your microcontroller's GPIO pins while delivering precise, jitter-free PWM output. Whether you're building a robotic arm, a hexapod walker, or an LED lighting system, this board is the go-to solution. Fast shipping, 7-day warranty on manufacturing defects, and dedicated technical support included.

Specifications

Key Features

• 16 Independent PWM Channels: Drive 16 servos, LEDs, or other PWM-controlled devices without using any MCU PWM pins.
• 12-Bit Precision: 4096 discrete steps provide ultra-smooth servo movement and fine-grained LED brightness control with zero visible flicker.
• Adjustable PWM Frequency: Tune from 24 Hz to 1526 Hz to match your application - standard 50 Hz for servos, higher frequencies for LED dimming or motor control.
• Simple I2C Communication: Uses only 2 wires (SDA & SCL) from your microcontroller, leaving remaining GPIO pins free for sensors and other peripherals.
• Chainable Up to 62 Boards: Six configurable address jumpers (A0-A5) allow you to connect up to 62 boards on a single I2C bus, controlling a staggering 992 PWM outputs.
• Separated Power Rails: Dedicated V+ screw terminal for servo power keeps high-current servo loads isolated from your delicate microcontroller logic supply.
• Built-In 220Ohm Series Resistors: Protects outputs and enables direct LED driving without additional current-limiting components.
• Plug-and-Play Servo Headers: Standard 3-pin male headers on each channel allow direct connection of hobby servos - no soldering or adapters needed.
• Broad Voltage Compatibility: Logic side operates at 3.3V or 5V, making it natively compatible with both 3.3V boards (ESP32, Raspberry Pi) and 5V boards (Arduino Uno, Mega).
• Compact Form Factor: Small footprint fits easily into robotics chassis, enclosures, and breadboard-based prototypes.
