I know it's a clumsy question, but I used to connect these to unregulated box mods, and DNA chips is kinda new to me. "If you look below the fire button you will see 4 small solder pads. Attach a 100 ohm resistor between the 2 pads on the left above the screen-printed 'F'. Resistor link Above the fire button, near the board edge and slightly off to the right, you will see 2 identical small solder pads. Attach your LED there, cathode side toward the middle of the board. That will give you what you want." the small solder pads are these two small circular parts ? just need a diagram because I can't imagine it, and what to do after that?!
