● If you want to make a robot which has lots of moving parts or if you want to control too many LEDs with PWM outputs, then the limited PWM outputs of your microcontroller would be a big problem for you. To overcome this problem, the only thing you should do is to get a 16-Channel 12-Bit PWM/Servo Driver.
● You can control 16 free-running PWM outputs with 16-Channel 12-Bit PWM/Servo Driver using only 2 pins. You can even chain up 62 breakouts to control up to 992 PWM outputs.
● It’s an I2C-controlled PWM driver with a built-in clock. That means you do not need to continuously send it to signal to tie up your microcontroller, it is completely free running!
● It is 5V compliant, which means you can control it from a 3.3V microcontroller and still safely drive up to 6V outputs. This is good 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.

Features :
● Adjustable frequency PWM up to about 1.6 KHz
● 12-bit resolution for each output – for servos, that means about 4us resolution at a 60Hz update rate
● Configurable push-pull or an open-drain output
● The output enable pin to quickly disable all the outputs
● Terminal block for power input
● Reverse polarity protection on the terminal block input
● Green power-good LED
● 3 pin connectors in groups of 4 so you can plug in 16 servos at once
● Chainable design
● A spot to place a big capacitor on the V+ line
● 220-ohm series resistors on all the output lines to protect them, and to make driving LEDs trivial.
● This board/chip uses I2C 7-bit address between 0x60-0x80, selectable with jumpers.
