PCA9685: 16 Channel 12-Bit PWM Servo Motor Driver
The PCA9685 is a 16-channel, 12-bit PWM (Pulse Width Modulation) servo motor driver module with I2C (Inter-Integrated Circuit) communication. It is commonly used with Arduino and other microcontroller platforms to control multiple servo motors simultaneously.

Product Details
Specifications:-
- This board/chip uses I2C 7-bit address between 0x60-0x80, selectable with jumpers
- Dimensions : 62.5 x 25.4 x 3 mm.
- Weight : 9 gm.
- Terminal block for power input (or you can use the 0.1" breakouts on the side)
- Reverse polarity protection on the terminal block input
- Green power-good LED
- 3 pin connectors in groups of 4 so you can plug in 16 servos at once (Servo plugs are slightly wider than 0.1" so you can only stack 4 next to each other on 0.1" header
- "Chain-able" design
- A spot to place a big capacitor on the V+ line (in case you need it)
- 220 ohm series resistors on all the output lines to protect them, and to make driving LEDs trivial
- Solder jumpers for the 6 address select pins
- i2c-controlled PWM driver with a built in clock. Unlike the TLC5940 family, you do not need to continuously send it signal tying up your microcontroller, its completely free running!
- It is 5V compliant, which means you can control it from a 3.3V microcontroller and still safely drive up to 6V outputs (this is good for when you want to control white or blue LEDs with 3.4+ forward voltages)
- 6 address select pins so you can wire up to 62 of these on a single i2c bus, a total of 992 outputs - that's a lot of servos or LEDs
- Adjustable frequency PWM up to about 1.6 KHz
- 12-bit resolution for each output - for servos, that means about 4us resolution at 60Hz update rate
- Configurable push-pull or open-drain output
- Output enable pin to quickly disable all the outputs
