Product Description

DIY KIT 16 Channel 12-bit PWM/Servo Driver-I2C interface-PCA9685 for arduino or Raspberry pi shield module servo shield

Product Description

• 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
