Hi!
Update!
As I see there are many boards for this solution, and I saw interest on this, I prepared a form to inform/check these solutions:
Form to inform about a Shield board to control several servos by PWM
I'll publish it here as I have enough information ;-)
I need to know how to handle more than 8 servos on a PWM with the same microcontroller.
Typical microcontroller boards are limited to 4 to 8 PWM outputs. So a shield board for this topic is needed. I'm checking it but not sure with what solution do it.
I want to control as much servos as possible with these boards (not at the same time):

I know the second one is not an "Arduino" board, but it has also a standard I2C bus, so the protocols and handeling are the same.
I saw some boards like these ones but I'm not sure which one to use:

Any help is welcome! Thanks in advance!
Good solution!
Hi Duane Degn!
I think it’s a good solution too! I saw your video on Youtube with the 32 servos and it’s nice to see and hear a good description. BTW, could you please post here the link to the exact board you used? I checked in the Parallax.com site and I found several but I’m not sure which is the one you used, sorry. Thanks!
Form to inform about shield boards
Hi all!
I just wrote a brief form to get information about the diferent solutions we are talking about here. If you wish please take some minutes to put the info there for all of us, thanks in advance!
