PCA9685 16 Channel 12-Bit PWM Servo Driver Breakout
Easily control servos or LEDs with the PCA9685 16 Channel 12-Bit PWM Servo Driver Breakout Kit from PMD Way.
You can control up to sixteen servos or LED channels via the I2C bus on your Arduino or other development platform with the great board.
Based on an open-source design by adafruit industries, you can daisy chain several boards by simply changing the I2C bus address on the second and subsequent board.
Terminal block and inline header pins are included but not soldered to the board. If you're using many servos and they experience jitter, solder an electrolytic capacitor whose value is (number of servos x 100 uF) or thereabouts.
