Convoy actually sent me 105D drivers for Biscotti development, and I calibrated it for those… but the production hardware was something else. FX-12 I think, by some other company. Very similar design, but with different components and pin 5 grounded. And some things didn’t work right.
FWIW, the 105D drivers had the worst 7135 chips I’ve ever used. So I’m glad those aren’t what he’s using now. The older 105C was much better, and the newer FX-12 is mostly better too. But the new drivers seem to randomly have different numbers of capacitors, and the grounded pin is an issue, and I hear people may still be getting the initial bad version sometimes… so I’ve been meaning to find out what’s up with that.
I’m kind of getting off topic though. It’s possible that the Gearbest product isn’t legit. It wouldn’t be the first time Gearbest has sold fake Convoy lights. But from what I hear, they usually have the real thing, I think, so it’s probably fine.
Edit: The “pill” is a piece of brass. It has other stuff inside, or attached to it. Generally a circuit board called a driver, some wires, and a solid metal board with LEDs on top, called the MCPCB (metal core printed circuit board). And some sort of reflector or optic on top, to focus the light, but it’s usually just sandwiched in there without being attached to anything.
