I guess mine are the 105C version:

Mine is the 105C version and pulls 0.28A on two-mode Low.
Is the PCB same for both 12F629 and ATtiny13?
I have not seen a PIC 12F629 on the Nanjg 105 so far.
Yes, sorry the 105A is like that. I am used to seeing the 105C. Actually the 105A is discontinued for quite some time.
Thanks for mentioning. Looking closely at the enlarged pictures I can see the letters "NY" on the MCU so I am confident that they are TINY13A.
Have ordered 3 pc.
According to the photo, the pin 4 of the MCU was connected to the ground which match the specification of Attiny13.
Hello guys ,
I wonder can I connect this driver to the LED missing one of the 7135 devices ? I want to reduce the power to about 2450mAh . Is this possible without physically removing of the 7135 device but just by soldering of the LED ignoring one 7135 ? And if this is possible - where on PCB should I solder the cables to the LED ?
Thank you very much in advance !
No, it's not, they are all connected in parallel.
However, you can cut a track leading one of them to disable a chip.
OK DrJones thank you ! Can you show me please which track should to cut and where on PCB should I solder the cables to the LED ?
If I were you I would just cut the legs off the 7135. Easier and less risk compared to accidental cutting wrong trace or overheat the board desoldering.
Today I received my driver. It`s 105C from DX ! I don`t know why but it works on half power ... High 1,4A , Mid 0,4A , Low 0,08A
I did solder all like on this photo. Any ideas why i can get the full power ?
Why did you solder the pins of the MCU like that and why haven't you used the stars to get your desired group of modes?
I didn`t touch the MCU ! I forgot to say ...
I see. You measured half on everything, Hi, Mid, Lo.
Maybe you can post some photos of that particular driver.
Yes ! Exactly the half on everything, Hi, Mid, Lo ! Don`t have photos of my driver yet but it looks exactly the same like this on the photo ...
I think that the 7135 devices from one on the sides of the PCB doesn`t work at all ....
Regulation test someone? Will be very grateful :)
