I had an XM-L glued to a heatsink and an 8xAMC driver (3.04A Nanjg105C from I.S.) with leads soldered to the emitter. I always double-check this kind of thing before committing to the next step. Hooked up an 18650; it lights up fine and I go through the first couple modes in the stock sequence. I set it down and came back to it with the soldering iron. I hooked it up to the same 18650 to see the shiny bright light before more soldering. Nothing.
I went ahead and soldered the bridge. Again, nothing. :~
I looked over the board and see that the 2 pins on the MCU (Tiny13A) don’t have the blob of solder like usual. Fixed that, still nothing :cry: … |(
I have must be missing something common or obvious. I’m waiting on more drivers in the mail but this is the last one I have for now
So, generous and handsome expert, check out the pics below. Anything?
