Specifications:The PCA9685 chip is wrapped in the center of the small board.It has power input terminal, green power indicator.It is convenient for you to insert 16 servo motors in 4 groups of 3-pin connectors at a time (the plug of the servo motor is slightly wider than 0.1", so you can put 4 pairs of 0.1" connectors).Reverse polarity protection of input on terminal block.Put a large capacitor on the V+ line (you will need it in some cases). The maximum external input voltage depends on this 10V1000uf capacitor.A 220ohm series resistor is placed on all PWM output lines to protect them and can easily drive the LED.Type: PCA9685 Drive ModuleVoltage: DC5-10V Power SupplyCommunication Interface: IICMaterial: PCBFeatures: Durable, Useful, Easy to InstallSize: 2.5cm x 6.1cm/0.98" x 2.4" (Approx.)Notes:Due to the light and screen setting difference, the color of item may be slightly different from the pictures.Please allow slight dimension difference due to different manual measurement.Package Includes:1 x PCA9685 Drive Module
