This is an I2C communication, 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 MCU!It’s 5V compatible, which means you can also use a 3.3V microcontroller to control and safely drive to 6V output (when you want to control white or blue lights, it’s OK to use 3.4 positive voltage)6 Address selection pin enables you to hang 62 driver boards on a single I2C bus, with 992 PWM outputs in total. That would be a huge resource.About 1.6kHz adjustable frequency PWM outputFor the stepper motor ready to output 12-bit resolution, which means that the update rate at 60Hz can reach 4us resolutionConfigurable push-pull output or open circuit outputThe output enable pin can quickly disable all outputs
