Description: Description 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 outputsWe 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 Package Included: 1 x New 16-Channel 12-bit PWM/Servo Driver -I2C PCA9685 For Arduino Contact usReturn PolicyFeedbackContact us For anything problem about product, price, shipping or order status, pleasecontact us via eBay message.Just contact us using the "Ask the seller a question" link on eBay.
