bit of wCK query

hey all, Ive been lurking around for a while (1 year 
!) and have finally decided on a robobuilder mainly for servo bus arch and the extra outputs on the wCK ( $ also helped 
).
which leads to my query..
My bot is in transit as we speak but I am curious on the level of output drive to the leds found in option servos?
I assume a driver Q -->led or is direct from servo processor..
and what level?
im hoping 5V because i need to drive 2 X hi current mosfets from the shoulder servos and logic level is always nice

I also believe they are 0~5V.
However if you got the transparent version, you will see that a resistor is soldered between the output port and the LED.
If you intend on using those ports you may need to "un-solder" the resistor.
The other alternative is replacing the servos you need with BLACK servos. The black ones don't have anything soldered on the DIO pin.
You can get the black servos here at Robosavvy.
