16-Channel 12-bit PWM/Servo Driver I2C interface PCA9685 for Arduino Raspberry Pi

PCA9685 is designed as a 16 channel 12-Bit PWM/Servo Controller, during which we are able to control 16 free-running PWM outputs with just two pins. Thereby greatly reducing the occupant I/Os. These drivers are widely utilized to make a robot that has several moving parts or if you would like to regulate too many LEDs with PWM outputs. During this case, the limited PWM outputs of your microcontroller cause an excellent big problem for you. Thus, this 16 channel PCA968512-Bit PWM/Servo Driver is the perfect solution for this problem. Moreover, it connects up to 62 driver boards in a cascade way. So it’ll be able to control 992 servos in total. This driver is an I2C-controlled PWM driver with an inbuilt clock. This indicates that there’s no ought to continuously send it to signal to hold up the microcontroller, it’s completely free running.

PCA9685 is designed as a 5v compliant device, that we will control it from a 3.3V microcontroller and still safely approach 6V outputs. This I2C-bus controlled LED controller is optimized for Red/Green/Blue/Amber (RGBA) colour backlighting applications. Each LED output provides an individual 12-bit resolution (4096 steps) PWM controller with a hard and fast frequency. The PCA9685 controller is designed to operate at a programmable frequency from a typical 24 Hz to 1526 Hz. It offers an adjustable duty cycle from 0% to 100%, in order that the LED set output a selected brightness. And also all the outputs are set to an equivalent PWM frequency. Additionally, PCA9685 allows staggered LED output on and off times to attenuate current surges. This on and off time delay are often programmed independently for every one of the 16 channels.
