Description Using only two pins, control 16 free-running PWM outputs! You can even chain up 62 breakout board to control up to 992 PWM outputs (which we would really like to see since it would be glorious) IIC input interface, PWM driver with a built in clock. That means that, unlike the TLC5940 family, you do not need to continuously send it signal tying up your MCU, its completely free running! Logic power supply 5V, which means you can control it from a 3.3V microcontroller and still safely drive up to 6V outputs (this is good for when you want to control white or blue LEDs with 3.4 forward voltages) Chain able design, 6 address select pins, so you can wire up to 62 of these on a single i2c bus, a total of 992 outputs – that’s a lot of servos or LEDs Adjustable frequency PWM up to about 1.6 KHz 12-bit resolution for each output – for servos, that means about 4us resolution at 60Hz update rate Configurable push-pull or open-drain output Output enable pin to quickly disable all the outputs On board 220ohm resistors can drive for LED output. R2 version use network resitor, optimized board layout. Add two extra pins V and VCC, can short connect to use same power. Documentation please see on this page.
