Adafruit 16-Channel 12-bit PWM Servo Driver with I2C Interface ADA0815 HUI7_W3NRX21

Key Features: i2c-controlled PWM driver with a built in clock Polarity protection on the terminal block input 3 pin connectors in groups of 4 so you can plug in 16 servos at once 220 ohm series resistors on all the output lines to protect them, and to make driving LEDs trivial Solder jumpers for the 6 address select pins You 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. Using only two pins, control 16 free-running PWM outputs! i2c-controlled PWM driver with a built in clock Polarity protection on the terminal block input 3 pin connectors in groups of 4 so you can plug in 16 servos at once 220 ohm series resistors on all the output lines to protect them, and to make driving LEDs trivial Solder jumpers for the 6 address select pins
