Adafruit 16-Channel PWM/Servo HAT & Bonnet for Raspberry Pi #AdafruitLearnSystem

The Raspberry Pi, while versatile, struggles with the precise timing needed to control servo motors. Adafruit is addressing that with a new 16-Channel PWM/Servo HAT or Bonnet—a small add-on board that handles servo control without taxing the Pi's processor. According to Adafruit Blog, the board can drive up to sixteen servos simultaneously over I2C using just two pins, with twelve-bit precision. And here's the clever bit: you can stack up to sixty-two of them to control up to nine hundred ninety-two servos from a single Raspberry Pi.
