DEVMO 2PCS PCA9685 PWM Servo Motor Driver I2C IIC Module 12-bit 16 Channel Compatible with Servo Ar-duino

Brand New- Using only two pins, control 16 free-running PWM outputs- You can even chain up 62 breakouts to control up to 992 PWM outputs- It's an i2c-controlled PWM driver with a built in clock- Using only two pins, control 16 free-running PWM outputs- You can even chain up 62 breakouts to control up to 992 PWM outputsUnlike the TLC5940 family, no need to continously send the signal- It's completely free running- Board runs with 5V DC current but has input voltage only for the servo motors- Separate voltage input allows you choose correct voltage for the application- Adjustable frequency PWM up to about 1.6 KHz- 12-bit resolution for each output- 4us resolution at 60Hz update rate- Configurable push-pull or open-drain output- Output enable pin to quickly disable all the outputs- Terminal block for power input (or you can use the 0.1" breakouts on the side)- Reverse polarity protection on the terminal block input- On board power indicating LED light
