Summary: This is a use i2c communication, built-in PWM drive and a clock. This means that it will be very different and TLC5940 series. You do not need to constantly send signals occupy your microcontroller! It is 5V compatible, which means you can also use a 3.3V microcontroller control and drive safely to 6V output (when you want to control a white or blue LED with 3.4 + positive voltage is also possible) 6 address selection pin so that you can put 62 driver board hanging on a single i2c bus, a total of 992 PWM outputs. It would be very large resources. About 1.6K hz Adjustable Frequency PWM output Ready to output 12-bit resolution of the stepper motor, which means the update rate of 60Hz can reach 4us resolution Configurable push-pull output or open collector output Output enable pin to quickly disable all output
Features: Central l PCA9685 chip was wrapped in a small plate l power input terminals l green power indicator l allowing you to group 3 at 4 pin connector 16 is inserted in a servo motor (servo motor plug slightly wider than the 0.1 ", so you can put four pairs of 0.1" connector) Reverse polarity protection l wiring board input l cascade design l V + line to place a large capacitor (in some cases you'll need) the maximum voltage depends on the peripheral input capacitance 10V1000uf l PWM output lines are all put a 220 ohm series resistor to protect them, and can easily drive the LED. Materials needed 1. Arduino Development Board 2. The steering gear 3. The number of needles DuPont 4. usb line
