Control 18 Servos


Can i use that with arduino duelminove to control 18 servo?

No, it has an internal oscillator instead of the GSCLK on the TLC5940.

And can you explain why that feature is important? What are the diference between gsclk and sclk?

The internal clock frequency of that part cannot be changed and its way too fast to be used to drive a servo.

Servos require a very specific range of control pulses and that chip is not capable of providing them.

Thanks :slight_smile:

I haven't tried this chip, but it's supposed to run 16 servos off a serial or I2C link.


Hi metRo_
What chip did you end up using?
I also would like to control 18 servos from an Arduino but I'm not sure what to use...

Thank you.
