16 Channel 12-Bit PWM/Servo Driver-I2C Interface PCA9685 Module for Raspberry Pi Shield Module Servo Shield for arduino DIY KIT

   Please read before buying: Because ordinary parcels do not have tracking information, so encountered the peak season of logistics, ordinary parcels will be extended to arrive, so if you mind the speed of logistics, please pay the registration fee, with faster logistics speed. When encountering slight product damage, bent pins, and scratches on the case, we will not accept refunds of disputes if they do not affect use. If you mind this situation, please do not purchase my product. When you buy my product, it is the default acceptance of this article! ! ! So we will not accept your dispute.    This is a use i2c communication, with built-in PWM drive and a clock. This means that it will have a very different and TLC5940 series. You don't need to constantly send signals to take up your SCM!    It is 5 V compatible, which means you can also use a 3.3 V single-chip microcomputer control and drive safely to 6 V output (when you want to control white or blue light may use 3.4 + positive voltage)    6 address selection that you can put the 62 driver pin board hung on a single i2c bus, a total of 992 road PWM output. It will be a very large resources.    About 1.6 Khz frequency modulation PWM output    Output 12 resolution for stepper motor, which means that at 60 hz update rate can reach 4 us resolution    Configurable push-pull output or open circuit output    The output enable pin can disable all output quickly    PCA9685 chip was wrapped in the middle of the small plate    L power input terminals    L green power light    L in four groups of 3 pin connector convenient you an insert 16 servo motor, servo motor plug slightly wider than 0.1 ", so you can put 4 to 0.1 "joint)    L input reverse polarity protection in a patch panel    L cascade design    L V + online placed a large capacitance (in some cases you will need) peripheral input voltage depends on the 10 largest v1000uf capacitance    L all PWM output line put a 220 ohm resistor to protect them, and can be easily drive leds.    1×PCA9685 Module        If need more parts Pls click  and submit the order.If you need more quantity,Pls contact us. If you mind the price,If some parts can not find out in my store,Pls contact us,we still have many parts don't published.    Please don't open dispute and leave any bad feedback, if you have any question, feel free to contact us,we will give you satisfactory answer. Hope you understand us, thank you in advance.    Your satisfaction and positive feedback is very important to us.
