nanjg 105D - schematic

Hello, I’m looking for the Nanjg 105D driver schematic for 6xAMC and 8xAMC, it’s all about this:

4.86€ |AMC7135 * 8 fahrer 3/5 modi Taschenlampe platine Anti reverse led treiber|flashlight driver board| - AliExpress
Page Not Found - Aliexpress.com
Someone has a schematic, I would be grateful if you would share it with me I know I can buy a ready-made driver. But I would like to order PCBs and solder the elements myself, then upload some software for 105D.

With the same components you could build a 3 channel driver, driving 3 banks of 7135’s.
Low = 1x 7135
Mid = 1x 7135 + 2x 7125 (3 in total)
High = 1x 7135 + 2x 7135 + 5x 7135 (8 in total)
The benefit would be that you don’t need PWM.
But you could use PWM for even lower modes (on 1x 7135)

Some googling found the schematic for the NANJG 105C which should be the same as the 105D, or very close.

djozz: I checked the 105C driver, unfortunately the 105D code doesn’t come under 105C: / that’s why I’m looking for some 105D solution

I’m not sure what “doesn’t come under 105C” means, but I’m not a code specialist anyway so perhaps someone else can answer this.

I meant that I have a 105C driver, I put code from 105D on it and it doesn’t work e.g. memory mode, after turning off it still lights up from moon. That’s why I was thinking about making my own driver under 105D and then I could understand it, because most of the codes are made under 105D.

Ah, a few things are different then.

Could you write something more about this solution, do you have any schematics or link?

From what I hopefully understood in this thread (link below) the 105c and 105d are very similar but with a few changes. It was evidently a creation of simons at convoy flashlights. Others have reprogrammed them so it can be done.

New 105D. replacing Nanjg-105c @ FT? (no stars!) Flashlight Modding and DIY Parts

I just got in an order from FT which included this item: 8* AMC7135 2-Group 2~5 Modes LED Flashlight Driver (Nanjg 105c) Instead this is what I received: [image] The top side looks nearly identical to the QLite and older Nanjg-105c I’ve got here. The silkscreen is not exactly the same as the older drivers. Other layers (copper, stop mask) may be the same, I don’t know. They are definitely close. I don’t know if it’s ‘official’ or a knockoff, but this layout should improve clearances on some…

I found a little more info here. I need a help with NANJG 105D driver program.

Edit: I missed the important part of your OP, you wanting to create your own pcb’s like the 105d. That’s why you need the schematic :person_facepalming: .

Maybe this could work for you? OSH Park ~
