Description

You want to make a cool robot, maybe a hexapod walking robot, or just a piece of art with lots of moving parts. You may also want to use the PWM output to drive many LEDs. Then you realize that your microcontroller has a limited number of PWM outputs! What's next? You can forget it or you can use this handy little PWM servo driver board.

This is an i2c communication, built-in PWM driver and a clock. This means that this will be very different from the TLC5940 series. You don't need to keep sending signals to occupy your MCU!

It is 5V compatible, which means you can also use 3.3V MCU control and ground drive to 6V output (3.4+ positive voltage is also possible when you want to control white or blue lights)

6 address select pins allow you to hang 62 driver boards on a single i2c bus, for a total of 992 PWM outputs. That would be a very large resource.

About 1.6Khz adjustable frequency PWM output

Prepare to output 12-bit resolution for stepper motors, which means 4us resolution at 60Hz update rate

Configurable push-pull or open output

Output enable pin to quickly disable all outputs
