Being the off-time cap it’ll be ok there since you have to remove it to flash anyway. I’m glad it’s there, not that it’s hard to out it between the pin and ground but it’s always nice to have a real pad for it. Looks good, I have a light that needs a 22mm driver, I have a contact board ordered but I’d love to order a set of these for it instead and test it, if your looking for someone send me the files and I’ll order 3.
Yeah, makes fine tuning the traces a pain but make for a cleaner render (but makes your head hurt from all that tweaking, re-tweaking, and tweaking some more)
either way, once it’s done it will be a POWERHOUSE of a driver…gonna make those XM-L’s cry for mamma
This will go into a F13 and other 22mm rigs right…I got mine in today
I did mention that in post #10. There’s plenty of copper there to solder to. I’ll probably leave both pads covered in the next version and remove the mask from at least part of the two big vias. If someone wants to solder to the small 1x1mm surface area they just need to scrape.
I was confused why there is a zener diode for a single cell flashlight driver. I'm guessing you're designing in options for use in other lights later on?
Well, really just for flexibility. Mainly as you say - in case someone wants to use it in a different light. Also though, someone might choose to run the F13 on a pair of 18350. Or if some battery manufacturer ever made a good 26350 :drool:
