16-Channel 12-bit PWM Servo Driver – PCA9685

Product Description

16-Channel 12-bit PWM Servo Driver – PCA9685

This powerful servo driver module enables you to control up to 16 servos or other PWM devices using only two I2C pins. It features a built-in clock, so you don’t need to continuously send signals to the microcontroller.

Key Features:

• Controls 16 PWM outputs using only two I2C pins
• Can be chained up to control up to 992 PWM outputs
• I2C-controlled PWM driver with built-in clock
• 5V compliant, can be controlled from a 3.3V microcontroller and drive up to 6V outputs
• 6 address select pins allow connection of up to 62 modules on a single I2C bus
• Adjustable frequency PWM up to about 1.6 KHz
• 12-bit resolution for each output
• Configurable push-pull or open-drain output
• Output enable pin to quickly disable all outputs

Includes:

• 4 pieces of 3×4 male straight header (for servo/LED plugs)
• 2-pin terminal block (for power)
• 6-pin 0.1″ header

Specifications:

• Dimensions: 2.5″ x 1″ x 0.1″ (62.5mm x 25.4mm x 3mm)
• Weight: 5.5 grams (without headers or terminal block)
• Weight: 9 grams (with 3×4 headers and terminal block)
• I2C 7-bit address between 0x60-0x80, selectable with jumpers
