Hi Everyone. I took on a recent project in building a led light panel for my sister. I am following the relatively simple instructions laid out in the youtube video published by DIY Perks - How to make a super bright LED light panel. I am at the step where I need to solder an external potentiometer to the trimpot (potentiometer) that is on the board of the step-down voltage regulator (szbk07) I purchased. Everything was going smoothly but the pins on the trimpot, where I need to be, has a unknown piece soldered between the exact 2 pins I need to utilize. Does anyone have a clue as to what this rectangular, ceramic colored insert - that is soldered between these two pins, is? My skills with solder are adequate. My concern is that when I head up these leads, that piece will shift or slide right out. Should I be worried? I do appreciate any advice or insight into this, as I contacted the seller & he is clueless to the nuances of the product he is selling.
