Description

Technical Specifications of PCA9685 Servo Shield Module

• Controller Chip: PCA9685 16-channel I2C-bus controlled PWM driver. (PCA9685 Servo Shield Module)

• Resolution: 12-bit resolution providing 4096 individual duty cycle steps.

• Frequency Range: Programmable PWM frequency from 24 Hz to 1526 Hz.

• Communication: Standard I2C interface compatible with 3.3V and 5V logic.

• Output Voltage: Drives outputs up to 6V for diverse servo types.

• Power Management: Includes a terminal block for external power supply input.

• Expandability: Chain up to 62 boards to control 992 outputs.

• Dimensions: Compact 62mm x 26mm PCB with standard mounting holes.

Usage and Hardware Setup

• First, connect the SDA and SCL pins to your microcontroller.

• Next, provide 5V to the VCC pin for the logic circuit.

• Then, attach an external 5V-6V power source to the green terminal.

• Plug your servos into the 3-pin headers in groups of four.

• Use this PCA9685 Servo Shield Module to offload PWM timing tasks.

• Afterward, set unique I2C addresses for multiple boards using address jumpers.

• Finally, initialize the Adafruit PWM Servo Driver library for easy coding.

Advantages and Disadvantages of PCA9685 Servo Shield Module

• Pros: Offloads timing-intensive PWM signals from the main microcontroller clock.

• Furthermore, it reduces wire clutter by controlling 16 channels via two pins.

• Cons: All 16 channels must operate at the same global frequency.

• Additionally, it requires an external power source for high-current servo loads.

Precautions and Installation Safety

• Warning: Never power high-torque servos directly through the Arduino 5V pin.

• Avoid reversing the polarity of the external power terminal block.

• Do not exceed 6V on the output pins to prevent damage.

What is Included in the Package

• 1x PCA9685 Servo Shield Module with built-in clock.

• 4x 3-pin male headers for easy servo connectivity.

• 1x 2-pin screw terminal block for external power input
