16 Channel 12-bit PWM/Servo Module – I2C interface

This modules uses the PCA9685 PWM chip to control up to 16 servos at once using the i2c protocol. Apart from using only 2 i2c pins on an arduino this module sends the servos constant pulses using a built-in clock. This eliminates the timing problems commonly associated with the native servo library.Characteristics:62mm x 26mmi2c address selectable by shorting out jumpers (default address: 0x40)Built-in 1000uF capacitor on the power lineInstalling the LibraryConnecting the module to an Arduino
