PCA9685 16-Channel 12-bit PWM Servo Driver Breakout/Shield for Raspberry Pi and other Microcontrollers is PWM driver with 12-bit resolution (4096 steps) for up to 16 separately controllable devices, up to 6 V operating voltage. There’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, it's completely free running! It is 5V compliant, which means you can control it from a 3.3V Arduino and still safely drive up to 6V outputs (this is good for controlling white or blue LEDs with 3.4+ forward voltages). 6 address select pins so you can stack 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

·         Terminal block for power input (or you can use the 0.1″ breakouts on the side)

·         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

·         Stackable design. You’ll need to pick up stacking headers and right angle 3×4 headers in order to stack on top of this shield without the servo connections getting in the way.

·         A spot to place a big capacitor on the V+ line (in case you need it)

·         Reverse polarity protection on the terminal block input

·         Green and red power-good LEDs

·         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

·         This board/chip uses I2C 7-bit addresses between 0x60-0x80, selectable with jumpers.
