HiLetgo 2pcs PCA9685 16 Channel 12-Bit PWM Servo Motor Driver IIC Module for Arduino Robot

What library do you need for the Arduino to control this? Any sample code?

What I2C address does this use? 0x40 like the Adafruit version?

V+ at the terminal block is not directly connected to V+ on the rest of the board. How do I get actual power to the servos?

What are the peak amps for this board?
