My current project is an automated lego car factory that uses an arduino R3 and a servo controller shield. Here's a video if you want to check it out.
It functions well and all, but I want to be able to controll it with a button or two, since the only way to do that now is to plug/unplug the cable or to click the restart button on the arduino.
Yes, a problem when you use a shield and you don't know which pins are uses and you can't solder.
A PCA9685 breakout board would have been better.
That shield you linked to uses the same chip for the servos (and has an additional motor driver).

No manual or papers what so ever were included and I've yet to find anything online. On the shield is the site "doit.am" but it's a chinese website that didn't really help.
For the use of Arduino IO you need to solder of the female header
[...]
The shield use digital input D6, D7, D11 and D12
There are numbers for the DI on the shield and only the four above aren't there. Soldering the 6 male connectors placed from DI0 to DI5 to their respective pin might just solve the problem. What do you think?
