16 Channel 12Bit PWM Servo Driver I2C Interface PCA9685
 16 Channel 12Bit PWM Servo Driver I2C Interface PCA9685 Rp. 222.000 Beli Lokasi : Jawa Timur Kondisi : New Posted on : 09-10-2016 14:10 Terjual : 0 barang telah terjual Dilihat : 18 kali Berat : 50 gram Last Sundul : 09 October 2016, 02:10:28 PM Penjelasan Produk Product 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 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
