Description:

I2C input, control 16 PWM output, you can control the 16 way servo motor.

Using only two pins, control 16 free-running PWM outputs; You can even chain up 62 s to control up to 992 PWM outputs

It's an i2c-controlled PWM driver with a built in clock.

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

Specification:

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 board with a couple nice extras

Terminal block for power input (or you can use the 0.1" s 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

Size: Approx. 60x 25x 5mm/ 2.36x 0.98x 0.20inch
