bought SKU 20017408006 12/24v step down to 5v regulator.
turns out to be adjustable not fixed. Which was the only reason I got this one. It is listed as 5v step down.
so obviously I had to change it, the picture shows cutting something the is circled in red on instructions. I have no idea what as i don’t see anything on board there. I made a small cut between 2 contacts that are partially in circled area. Plugged board in and in fried and smoked. Please let me know what I am supposed to cut to be able to use this as a 5v step down ( as I was lead to believe by the name ‘DROK DC 12v 24v Step Down to 5v Buck Converter Board’)
