3 Pcs PCA9685 16 Channel 12 bit PWM Servo Driver for Arduino Raspberry Pi IIC Interface Shield

This is an i2c-controlled PWM drive and a built-in clock. This means that it will and TLC5940 series are very different. It is 5V compatible, which means you can also use 3.3V MCU control and safely drive to 6V output (when you want to control white or blue LEDs with 3.4+ positive voltage is also possible) Address select pins so you can put 62 driver board hanging on a single i2c bus, a total of 992 PWM outputs. That would be a very large resource. About 1.6Khz Adjustable Frequency PWM output Output Enable pin to quickly disable all output
