(170)16Ch PWM/Servo/Servo Driver Board Controller IIC PCA9685 MMD

This is a built-in PWM driver and a clock using i2c communication. This means that this will be very different from the TLC5940 series. You don't need to constantly send signals to occupy your microcontroller!<br> It is 5V compatible, which means you can also control it with a 3.3V microcontroller and safely drive it to the 6V output (3.4+ positive voltage is also ok when you want to control the white or blue LEDs)<br> The 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 would be a very large resource.<br> About 1.6Khz adjustable frequency PWM output<br> Ready to output 12-bit resolution for stepper motors, which means 4us resolution at 60Hz update rate<br> Configurable push-pull or open-circuit output<br> Output enable pin quickly disables all outputs<br> The PCA9685 chip is wrapped in the center of the small board<br> Power input terminal<br> Green power indicator<br> It is convenient for you to insert 16 servo motors at a time in 4 sets of 3-pin connectors (the plug of the servo motor is slightly wider than 0.1inch, so you can put 4 pairs of 0.1inch connectors)<br> Input reverse polarity protection on terminal block<br> Cascade design<br> Put a large capacitor on the V+ line (you will need it in some cases) The peripheral input voltage depends on this 10V1000uf capacitor<br> Put a 220 ohm series resistor on all PWM output lines to protect them and drive LED easily.<br> Colour: blue<br> Material: PCB<br> Size: 60x25mm<br> Package Contents:<br> 1 * Servo driver board<br> Only the above package content, other products are not included.<br> Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
