TECNOIOT 2pcs PCA9685 16 Channel 12 bit PWM Servo Driver I2C Interface

x2pcs PCA9685 16 Channel 12 bit PWM Servo Driver I2C Interface for Arduino Raspberry Pi DIY Servo Shield Module 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 Features - 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 PACKET CONTAINS: 2pcs x PCA9685 Module
