16 channel 12 bit PWM servo board using PCA9685 Zoom

16 Channel Servo Motor shield for Robot or Lighting LED effects

16 Channel Servo Controller shield, fully assembled with stackable headers.

Availability: In stock



Product Description


    Using only two pins, control 16 free-running PWM outputs!  You can even daisy chain up to 62 boards to control up to 992 PWM outputs.

    It's an i2c controlled PWM driver with a built in clock, this frees your micro from boring refresh cyles.

    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 drive  white or blue LEDs with 3.5+ forward voltages)

    6 address selection pins allow you to wire up to 62 of these on a single i2c bus, a total of 992 outputs - please send picture when you do this.

    Adjustable frequency PWM up to about 1.6 KHz.

    12-bit resolution for each output - for servos, that means about 4us resolution at 60Hz refreshy rate.

    Configurable push-pull or open-drain output.

    Output enable pin to quickly disable all the outputs


     Stackable Pin headers.

    Terminal block for power input (or you can use the 0.1" breakouts on the side), but that will be a current issue if you use servos.

    Reverse polarity protection on the terminal block input, dont forget typical forward voltage drop 1 volt.

    Green power 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

    Daisy chainable design.

    A spot to place a big capacitor on the V+ line (in case you need it). We will include a 220uf at 25 V.

    330 ohm series resistors on all the output lines to protect them, and to make driving LEDs easy.

    Solder jumpers for the 6 address select pins.
