Hi guys. I'm jumping into building a saber with both feet, and a have a couple of questions. One, with a 7.4v Li-ion 2600mAh 18650 power source, and using the color extender board for the petit crouton, will I need resistors for the LED? What is the default output voltage on the main LED channels on the petit crouton?(So I can find the correct resistors) And does anyone have a map of which pads correspond to which color on the LED?

Thank you in advance.
