Anyone know how to connect a SparkFun PWM shield to drive servos?

Hi all,

I've got a SparkFun PWM shield that I would like to use to drive 8 servos and maybe some lights, and am unsure how to wire it up correctly.

It came with no documentation, and my online searches have not yielded any useful results. I thought I'd try here for some real experts! I'm sure one of you have used one successfully.

I'll write the code later, but first I'd like to understand how to wire it up correctly to make sure my project will be feasible.

I have some small 5 gram 3-6V Hextronix HTX500 servos. I'll be using 8 of them in this project, and will need to power them separately from my Arduino.

Has anyone successfully used one of these boards to drive a number of servos?

Pat.

If it's a "shield", how could anyone get it wrong? (:

Yeah, I know... but its got Vin options, selection switches/jumpers, places to include optional resistors... An a number of posts from users that have set it up wrong and fried it. Just thought I'd check to see if anyone here has used it before I fry mine!
