Hi all
is it possible to disable all mods on nanjg 105 and make it one mod HIGH mod only ?
Sure if you can flash it, but why not just bypass the driver for direct drive? Just move the LED - lead to ground.
Direct drive is not a good idea unless your making a hot rod light. Led on a noctigon or similar, batteries that can safely handle high amps.
If you use a nanjg flashed for high mode only you can retain the low voltage detection. RMM / mtnelectronics.com would likely be able to make you one.
You could always stack chips on this
Shorting one of the pwm pins will give you high only(full output of all chips) but you lose low voltage protection since the mcu no longer controls the chips and cannot step down the output.
flash it mean reprogram it ?
Rufusbduck i think you just told me what i want but you can you draw it and tell me which pins to short ?
Short orange pad to any Vdd pin(red)
Orange pad and D1 pad next to it(line side) are the same and that closest red pin is the easiest to short with a dab of solder.

You missed C1 to Vdd. 
Thank you i tried it, it is working just fine it solved me a Big problem
