DescriptionSpecificationsThe 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 3pin 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 maimum eternal 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 DC510V Power SupplyCommunication Interface IICMaterial PCBFeatures Durable, Useful, Easy to InstallSize 2.5cm 6.1cm0.98 2.4 Appro.NotesDue 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 Includes1 PCA9685 Drive Module
