DIY 16 Channel PWM Servo Motor Controller for Arduino, PCA9685

1. Works with official Arduino boards
2. This is an I2C controlled PWM driver board with a built-in clock
3. You can use a 3.3V MCU to control and drive the output up to 6V.
4. 6 address select pins allow you to connect 62 driver boards to one I2C bus, for a total of 992 PWM output channels
5. PWM output with frequency modulation of about 1.6KHz
6. The PCA9685 chip is at the heart of the board
7. With power input terminal
8. With green power indicator light
9. Convenient to insert a total of 16 servos at the same time
10. With reverse polarity protection for input
11. Waterfall design
12. Put a large capacitor on the V+ line
13. Put 220 ohm resistor components on all PWM output lines
