Onyehn PCA9685 IIC Module,16 Channel 12-Bit PWM Servo Motor Driver for Arduino Robot or Raspberry pi(4 Pack)

Onyehn PCA9685 IIC Module,16 Channel 12-Bit PWM Servo Motor Driver for Arduino Robot or Raspberry pi(4 Pack)

• 🌟Communication Interface: IIC.
• 🌟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.
• 🌟Adjustable frequency PWM up to about 1.6 KHz;Configurable push-pull or open-drain outputManufacturer.
• 🌟12-bit resolution for each output - for servos, that means about 4us resolution at 60Hz update rate.

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!<br> Output enable pin to quickly disable all the outputs.<br> Terminal block for power input (or you can use the 0.1" breakouts on the side).<br> Reverse polarity protection on the terminal block input.<br> Green power-good LED.<br> 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.<br> "Chain-able" design.<br> A spot to place a big capacitor on the V+ line.<br> 330 ohm series resistors on all the output lines to protect them, and to make driving LEDs trivial.<br> Solder jumpers for the 6 address select pins.<br><br> <b>Package Include:</b><br> 3 * PWM Servo Motor Driver<br>
