New 105D. replacing Nanjg-105c @ FT? (no stars!)

I can take better pictures, but is there a reason to? This one is already detailed. The other side looks just like a 105c, I will post a picture of that if it’s somehow helpful. What, specifically, do you need?

IMO you should not expect to find a cheaper 8x7135+ATtiny13A driver than the ones on FT, at least in the quantity you are talking about. I think it’s fair to assume that the cost to manufacture this 105D. driver is not significantly different from the cost to manufacture a 105c. My assumption is that FT had the option to order a driver with “improved fitment” and took it without realizing the downside.

For me - yes. Would appreciate it a lot
I sometimes do quite heavy modifications to the 105C, with lots of trace cutting and rearranging, so I’d like to know if I can do all this to 105D.

Good pics of both sides, perpendicular to the PCB plane. Something similar to the original FT driver pics from their product page. IC markings, traces, all that stuff.

IC markings are the same. I checked. I did not check resistor values or the Vf of the diode.

I will strip one soon, how about I just take pictures of the bare PCB after it’s stripped?

Suits me perfectly, thanks!

105D Hopefully it is good. I just stocked up 5 pieces last week.

Unfortunately they never update it with 4 modes like Qlite.

That’s what I thought, but I still wonder if this is something that will be sold on its own merits (sold as Nanjg 105d) or if it is just being slipped in to the place of the 105c.

Good question, I wonder the same thing.

Crap, just noticed I got the same ones last week. I wanted to use the stars for OTCs… propobly gonna strip them for parts now.

Didn’t even notice that time, I’ve ordered them on 11.11. (105c 2 Group 2,8A)

Edit: My Convoy M2 I got today from FT has the same driver inside. I’d realy like to get my solder points back where they belong.

Created a ticket at FT, maybe they’ll sort it out.

Simon should know about these drivers then.

FYI, have manged to get a 5$ gift card (had 5 pcs).
Okay for me so far, didn’t want to spend any more time on this.

Don’t know what I’ll use the drives for, except it will most likely be in a flashlight.

Thanks for the info, Simon!
Is it 2-group (3/5 modes), like before?

yes ,the stars is useless ,so i removed them
and of course i also have four groups version (with stars)

So, the 105d is YOUR design? Are they for sale anywhere alone?

Nice! Though I do prefer the old way of soldering star than the updated 2 group version. The way it flashes once on low in three mode, always distracting.

I agree. I strongly dislike the blink/flash - it is startling.

and i have old 7135 verison ,
i also have LD25 with hidden strobe .
i think LD25 is better,no pwm

Yeah, if the blink could just be a quick 25% reduction in output (slight PWM drop then back up) rather than a full off/on flash that would be alot better

LD-25 Page Not Found - Aliexpress.com

no ,not this version ,the mode of LD25 in my stock is different ,
it’s
Lo (80mA) > Mid (700mA) > Hi (3000mA);
Double half-press: Strobe
