Adafruit 16-Channel 12-bit PWM/Servo Driver Breakout- I2C interface - PCA9685 Motor Control any 3-pin classic DC hobbyYou want to make a cool robot, maybe a hexapod walker, or maybe just a piece of art with a lot of moving parts. Or maybe you want to drive a lot of LEDs with precise PWM output. Then you realize that your microcontroller has a limited number of PWM outputs! What now? You could give up OR you could just get this handy PWM and Servo driver breakout. When Adafruit saw this chip, they quickly realized what an excellent add on this would be. Using only two
