16-Channel 12-bit PWM/Servo Driver - I2C interface - PCA9685, RoHS

Pololu Micro Maestro 1350 is a compact, versatile servo controller with a USB interface and autonomous operation capability, designed for use in robotics, animatronics, and control systems based on PCs or microcontrollers. Thanks to its flexible channel configuration, it can also be used as a sensor interface and I/O expander.

The motor driver card can drive 24 servo motors at most. It can be used to drive a multiple-joint robot machine, such as Hexapod Robot, Biped Robot, and Arm Robot. P0288

Adafruit 16-Channel PWM / Servo HAT for Raspberry Pi - Mini Kit (Adafruit 2327)

Servo control module with 180 degree range of motion, No programming required and is ideal for operations such as opening and closing the mouth, hands or eyes. Control is performed using the built-in ATTiny13A, button and potentiometer, and each pressed button moves the servo to the other end of the range, with the possibility of adjusting the length of the movement. Kitronik 2177

This Kit with fully-dedicated PWM driver chip handles all the motor and speed controls over I2C. Only two data pins (SDA & SCL in addition to the power pins GND & 5V) are required to drive the multiple motors; you can also connect any other I2C devices or shields to the same pins. This  makes it drop-in compatible with any Arduino, such as the Uno, Due, Leonardo and Mega R3. Adafruit 1438
