The PCA9685 16-channel 12-bit PWM/Servo Driver is a module that can be used to control up to 16 servo motors or other PWM-controlled devices using pulse-width modulation (PWM). It is controlled using an I2C interface, which means it can be connected to a microcontroller or single-board computer using just two wires. The PCA9685 module has a built-in processor that generates the PWM signals and sends them to the output channels. Each channel can be independently controlled, allowing you to control multiple motors or other devices with a single module. The module can generate PWM signals with a frequency of up to 1.6 KHz and a resolution of 12 bits, which allows for very precise control of the motors or other devices. The PCA9685 module is often used in robotics projects and other applications where multiple PWM-controlled devices need to be controlled from a single microcontroller or computer. It is a convenient and easy-to-use solution for controlling servo motors or other PWM devices, and it is compatible with a wide range of microcontrollers and single-board computers. Want to make a hexapod walker? Maybe you're making a piece of art with tons of moving parts, or you need to drive a ton of LEDs with precise PWM output. Your microcontroller has a limited number of PWM outputs, and you find yourself running out! Not with the Adafruit 16-Channel 12-bit PWM/Servo Driver - I2C interface. With this pwm and servo driver breakout, you can control 16 free-running PWM outputs with just two pins! Need to run more than 16 PWM outputs? No problem. Chain together up to 62 of these beauties for up to an outstanding 992 PWM outputs.
