By attaching two identical resistors, you split the voltage in half: seen in the X and 1/2 X on the board.
You can also use two different resistor values to create a variety of voltage ratios across the board: http://www.ohmslawcalculator.com/voltage-divider-calculator
Included are 3 PCBs, shipped via USPS first class (w. tracking).
Great for DIY!

I am not responsible for any outcomes involved in using this board. It is designed for one purpose only, dividing a signal voltage. Do not apply current through the board.
