Hello, I have a 11.1v LiPo battery which I want to use to supply power to servos (11.1v) and to a microcontroller (5v). I posess a pololu S8V3A voltage regulator, but no idea on how to wire the battery to it and how to make 1 battery to supply 2 power lines with different voltages. I have little experience in electronics and would be happy to get an advice or directions to get this stuff done.
Hello, Soth1985. What voltage do you want to supply to the servos? How many servos are there, and do you have any technical information about them? You wrote “11.1V” in parentheses but that seems wrong. Typical servos can be powered from 5 V, so maybe you could use one of our Pololu Step-Down Voltage Regulators to power some servos and your microcontroller:

Hi, it`s AX-12 Robotis Dynamixel servos and 11.1v is ok for them.
Ok, then you can power the servos directly from the battery and power the microcontroller through the Pololu Step-Up/Step-Down Voltage Regulator S8V3A that you already have.
