About this product
PCA9685 is a 16-channel, 12-bit PWM driver board controlled over I2C, which frees the microcontroller from generating PWM signals itself. It is used to drive multiple RC servos or LED channels in robots and multi-joint projects. The board supports 3.3 V and 5 V logic and several boards can share the same I2C bus.

How do I control servos from an Arduino using this board?
Connect SDA and SCL to the Arduino I2C pins (A4 and A5 on an Uno), power the logic side from 5V and GND, and connect the servos to the channel headers. Use a separate 5 V to 6 V supply on the V+ terminal for the servos and share the ground with the Arduino.
Should the servos be powered from the board or from an external supply?
Use an external supply for the servos. Servos draw much more current than the logic circuitry, so powering them from the Arduino 5V pin can cause resets or brownouts. Keep the grounds connected.
