Описание товара
You want to make a cool robot, maybe a hexapod walker, or maybe just a piece of art with a lot of moving parts. Or maybe you want to drive a lot of LEDs with precise PWM output. Then you realize that your microcontroller has a limited number of PWM outputs! What now?
Using only two pins, control 16 free-running PWM outputs! You can even chain up 62 breakouts to control up to 992 PWM outputs
>It's an I2C-controlled 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 microcontroller, its completely free running!
>It is 5V compliant, 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)
>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
We wrapped up this lovely chip into a breakout board with a couple nice extras
>Terminal block for power input (or you can use the 0.1" breakouts on the side)
>Reverse polarity protection on the terminal block input
>Green power-good LED
>3 pin connectors in groups of 4 so you can plug in 16 servos at once (Servo plugs are slightly wider than 0.1" so you can only stack 4 next to each other on 0.1" header
>"Chain-able" design
>A spot to place a big capacitor on the V+ line (in case you need it)
>330 ohm series resistors on all the output lines to protect them, and to make driving LEDs trivial
>Solder jumpers for the 6 address select pins
