#2988: 16 Channel Servo Shield (12bit PWM/Servo Driver-I2C Interface PCA9685)


A servo shield is a device that allows you to control multiple servo motors with your Arduino board. This 16 channel servo shield is a specific type of servo shield that can control up to 16 servo motors using a 12-bit pulse width modulation (PWM) signal and an I2C interface. The PCA9685 chip on the shield is what allows it to control the servos using the I2C interface.

To use the servo shield, you will need to connect it to your Arduino board and then connect your servo motors to the appropriate channels on the shield. You can then use the Arduino programming language to send control signals to the shield to move the servos to specific positions.

There are a number of libraries available that make it easy to control servo motors using an Arduino board and a servo shield. These libraries often include functions for setting the position of the servos, as well as functions for moving the servos to specific positions over time (for example, to create smooth movement).


Build the ultimate robot or servo control system with this Arduino Shield.

Using only two pins, control 16 free-running PWM outputs! You can even chain up 62 breakouts to control up to 992 PWM outputs in total!

Product Details

• It's an i2c-controlled PWM driver with a built in clock. That means that, 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
We wrapped up this lovely chip into a breakout board with a couple nice extras
• 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)
• 330 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
