Introduction:
This is a communication using i2c, built-in PWM driver and a clock. This means that this will be very different from the TLC5940 series. You do not need to constantly send signals occupy your microcontroller!
It's 5V compatible, which means you can also control and safely drive a 6V output with a 3.3V microcontroller (it's also okay to control the white or blue LEDs with a positive 3.4+ voltage)
6 address select pins allow you to hook up 62 driver boards on a single i2c bus for a total of 992 PWM outputs. That will be a very large resource.
About 1.6Khz FM PWM output
Ready for stepper motor output 12-bit resolution, which means that the 60Hz update rate can reach 4us resolution
Push-pull output can be configured or open output
The output enable pin quickly disables all outputs

characteristic:
PCA9685 chip is encapsulated in the small central plate
power input terminal
green power indicator
Four 4-pin 3-pin connectors allow you to insert 16 servo motors at a time (the servomotor plug is slightly wider than 0.1 ", so you can fit four pairs of 0.1" connectors)
reverse polarity protection input patch panel
cascade design
Put a large capacitor on the V + line (you will need it in some cases) The maximum input voltage on the periphery depends on the capacitance of this 10V1000uf
All PWM output lines put a 220 ohm series resistor to protect them, and can easily drive the LED.
