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 :)
It is most likely a bad connection between the two sides of the print. All 7135 should be connected in parallel. Try with an ohmmeter or a continuity tester between corresponding legs of one 7135 on the upper side and one on the lower side and repair the missing connection (if any).
So, no regulation? I've tried to measure ohm of my Trustfire with my UNI-T and got 0.
Thank you for the advise my friend ! Will test and report here !
