Custom PCA9685 16 Channel 12 bit PWM Servo Motor Driver I2C IIC Module for MG90S SG90 MG995

You want to make a cool robot, maybe a six-legged walking robot, or just a piece of art with lots of moving parts. You may also want to drive many LED indicators with a precise PWM output. Then you realize that your microcontroller has a limited number of PWM outputs! So what are we going to do? You can give up or you can use this handy PWM servo drive small board.

■ It is an i2c communication with a built-in PWM driver and a clock. This means that it will be very different from the TLC5940 series. You don't need to keep sending signals to occupy your microcontroller!
■ It is 5V compatible, which means you can also use 3.3V MCU control and safely drive to 6V output (3.4+ positive voltage is also possible when you want to control white or blue indicators)
■16 address selection pins enable you to hook 62 driver boards to a single i2c bus, with a total of 992 PWM outputs. That would be a huge resource.
■ Approx. 1.6Khz PWM output
■ Prepare the output 12-bit resolution for the stepper motor, which means that 4us resolution can be achieved at an update rate of 60Hz
■ Configurable push-pull output or open circuit output
■ Output Enable pins quickly disable all outputs

● The PCA9685 chip is wrapped in the center of the small board
● Power input terminal
● Green power indicator
● Easy to insert 16 servomotors at once in 4 sets of 3-pin connectors (the plugs of the servomotors are slightly wider than 0.1", so you can put 4 pairs of 0.1" connectors)
● Reverse polarity protection for input on the patch board
● Cascade design
● Place a large capacitor on the V+ line (in some cases you will need) the maximum voltage of the peripheral input depends on this 10V1000uf capacitor
● Put a 220 ohm series resistor on all PWM output lines to protect them and drive the LED easily.
