Hi and welcome to dronetrest 
As for connecting servos to your KK2 board could you give me some more details, are you using it on a multirotor of airplane? Also most ESC have a Ubec built in so that will provide power for your KK board and also to any servos you connect to it.
Thy for reply I am using the servo on a tri copter so i am safe enough connecting to kk2 board
