Product Description
* 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!
* • 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
Feature
1. The PCA9685 chip is wrapped in the center of the small board
2. Power input terminal
3. Green power indicator light4. In 4 sets of 3-pin connectors, it is convenient for you to insert 16 servo motors at once (the plug of the servo motor is slightly wider than 0.1 ",
so you can place 4 pairs of 0.1" connectors)
5. Reverse polarity protection for input on the terminal block
6. Cascade design
7. Place a large capacitor on the VI line (which you may need in certain situations), and the maximum external voltage depends on this 10V1000u capacitor
8. All PWM output lines are equipped with a 220 ohm series resistor to protect them and easily drive LEDs.
