PCA9685 with external power supply

Sun Sep 15, 2019 8:20 am

Hi, I'm working on a project in which I need 14 servos, that's why I think I should use a PWM extension like PCA9685.
The problem is that not all the servos need the same Voltage. Some of them need 5v, others 7v and others 24v.

I'd like to know if it's possible to do what is shown in the attached image and, if not, what solution do you suggest?

Thanks in advance!
