• Servo Driver PCA9685 16-Channel 12-bit PWM  I2C interface

PCA9685 module is a great 16 Channel Servo Motor Driver for building humanoids, bipeds, hexapods, rc quadcopters or Animatronics projects etc. It is used to control upto 16 servo motors with just two pins of the Arduino, Raspberry Pi or any other microcontroller with I2C. Controlling the servos is simple and easy. Servos can be plugged in directly to the board with no additional circuits or connectors required.

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
