DONGHENG 5PCS 16 Channel PWM/Servo Driver IIC interface-PCA9685 for arduino or Raspberry pi Shield Module servo Shield
Description
- 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
Product description 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! 1.Output enable pin to quickly disable all the outputs 2. Terminal block for power input (or you can use the 0.1" breakouts on the side) 3. Reverse polarity protection on the terminal block input 4. Green power-good LED 5. 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 6. "Chain-able" design 7. A spot to place a big capacitor on the V+ line 8. 330 ohm series resistors on all the output lines to protect them, and to make driving LEDs trivial 9. Solder jumpers for the 6 address select pins
