PCA9685 16 Channel 12-bit PWM Servo motor Driver I2C Module For Servo Arduino US

Product Introduction： Want to make a hexapod walker? Maybe you're making a piece of art with tons of moving parts， or you need to drive at on of LEDs with precise PWM output. Your microcontroller has a Limited number of PWM outputs， and you find yourself running out! Not with the Ada fruit 16-Channel 12-bit PWM/Servo Driver-I2C interface. With this pwm and servo driver breakout， you can control 16 free-running PWM outputs with just two pins! Need to run more than 16 PWM outputs? No problem. Chain together up to 62 of these beauties for up to an outstanding 992 PWM outputs. Features： Dimensions(no headers or terminal block) 2.5"x 1"x 0.1"(62.5mmx 25.4mmx3mm) . Weight(no headers or terminal block) ：5.5grams Weight(with 3x 4 headers & terminal block) ：9grams This board/chipusesI2C 7-bit address between 0x 60-0x 80，selectable with jumpers Terminal block for power input(or you can use the 0.1"breakouts on the side) Reverse polarity protection on the terminal block input.Green power-go
