The only change I can see on Rev 2 is a slight shift of the Zener diode with larger solder pads. My original BLF17DD Z is exactly the same except for that one component. I’ve used several of them and like how they work. I AM finding though that some of the components on these boards tend to be very close to the outer edges of the board, possibly making contact with the shelf in the pill that is normally used for grounding purposes. Just have to make sure that shelf is very narrow and doesn’t cause conflict. I had also been laying the Zener on it’s side around the cap instead of stacking it, for the clearance and ease of soldering. I’ve been using pretty much nothing but BLF boards since all this started, on everything. I DID utilize a Qlite once recently and had thoughts that I might have forgotten how to stack a chip…

K, thanks! Funny, I just did the same exact thing - laying the diode on it's side.

See my new BLF17DD ref thread: https://budgetlightforum.com/t/-/27210. You and several others I'm sure don't need it now, but I'm trying to keep an online ref, specially for those this is all new to. If you notice anything amiss or may be needed there, shoot me a pm. Trying to keep the thread uncluttered. But the idea is to use the OP as a one source reference for the BLF17DD versions.
