SMAKN 16 Channel PWM Servo Driver IIC interface-PCA9685 for arduino or Raspberry pi shield module servo shield

*PCA9685 chip was wrapped in the middle of the small plate. *Power input terminals. *The green power light. *Reverse polarity protection input in a patch panel. *3 pin connectors in groups of 4 so you can plug-in in 16 servos at once (Servo plugs are slightly wider than 0.1 "so you can only stack 4 next to each other on 0.1" header. *Cascade design. *V + online to place a large capacitance, peripheral input maximum voltage depends on the 10 V 1000 uf capacitance, all PWM output line put a 220 ohm resistor to protect them, and drive leds easily. Specifications: *Size: 25 mm * 62 mm. *Weight: 11 g. *Voltage: DC5-10V power supply. *Communication interface: IIC. *16 road steering gear control.
