💎【PCA9685 16 Channel 12 bit PWM Servo Motor Driver I2C IIC Module】: This is a PWM driver and a clock built in, using I2C communication. This means that it will be very different from the TLC5940 series. You don't need to keep sending signals to occupy your microcontroller
⚡It is 5V compatible, which means you can also use a 3.3V microcontroller to control and ground drive to the 6V output (when you want to control white or blue lights with 3.4+ positive voltage is also possible)
🥇It is convenient for you to insert 16 servo motors at a time in 4 groups of 3-pin connectors (the plug of servo motor is slightly wider than 0.1", so you can put 4 pairs of 0,1" connectors)
🥈The 6 address selection pins allow you to hook up 62 driver boards on a single I2C bus for a total of 992 PWM outputs. That would be a very large resource.
🥉You want to make a cool robot, maybe a six-legged walking robot, or just a piece of art with many moving parts. You may also want to use the PWM output to drive many LED indicators. Then you realize that your microcontroller has a limited number of PWM outputs! What do you want to do next? You can give up or you can use this handy little PWM servo driver board.
