PCA9685 16-Channel 12-bit PWM Servo Motor Driver I2C Module For Arduino

This PCA9685 16-Channel 12-Bit PWM Servo Driver can help a lot when there are insufficient PWM output pins for the MCU in your project. Make a robot, hexapod walker, or drive multiple LEDs with precise PWM control. Using only two pins, control 16 free-running PWM outputs! You can even chain up 62 breakouts to control up to 992 PWM outputs. Simply enable the I2C communication between the MCU and the PCA9685 16-channel 12-bit PWM driver, so as to control multiple servos simultaneously. Features: i2c-controlled PWM driver with a built-in clock. That means that you do not need to continuously send it a signal, tying up your microcontroller. It is completely free running! 5V compliant, 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 Adjustable frequency PWM up to a
