Ok, then I will have to find me someone to add firmware.
In fact with protected cell the risk of a short to the battery gets lower, as the thin metal strip from the minus gets on most to the top
Unprotected cells I double or triple heat shrink so they fit better
Thank you Soooo much Lexel, you saved me alot of time and effort because I was learning to use Eagle in the past 2 days
so far this is my progress :person_facepalming: :cry:
I have many Nanjg 105D Drivers, like this one
Can I install their Components on your Driver ?
if not, Could you share the Needed Components for the Driver Please, or even a Nanjg 105D .sch file would be Greatly Appreciated
Thanks
I’m subbin’ this one! :+1:

105D driver should work with Tripledown layout, same pin for the 7x AMCs
R5, C1 and C2 are to filter voltage spikes from the MCU, at least R5 you have to bridge or equip with 4.7Ohm resistor
Lexel: djozz:That is very quick Lexel, thanks! Are all 8 7135 chips in parallel or is this a triple channel driver with one 7135 with its own channel? It is relevant because I would like to simply transfer the components (except the FET) of a BLF-A6 driver to this board and make that work directly (I can not do anything related to flashing firmware myself).
I made the board for Tripledown layout
the first I posted had the pins not as the A6
Ok, then I will have to find me someone to add firmware.
I made a Fet+ n 7135 one, should be pin compatible to A6
Pin 4 FET pin 5 AMCs

That is wonderful Lexel, if built up one-sided I can even use 2 chips and have up to 700mA regulated (mode spacing with A6-firmware should not be too bad)! I ordered 3, will check them out, and report here.
I’m not sure if I’m a rare exception: can solder very well but can’t do computer stuff. For this board I can just rob all components off a common BLF-A6 board (or BLF X5/X6 board) and that is all there is to it.
I just realized that the Fet +n has wrong pinout compared to A6
it happens .
we will wait your fixed Version
Thanks for the Updates Lexel
I fixed the Fet+ n 7135 one, should be pin compatible to A6 now
Pin 6 FET pin 5 AMCs

Many thanks lexel, helpful as always :+1:
Good that you noticed the mistake, ordered again
Luckily Oshpark is dead cheap for these little boards…
will the OSRAM 4715AS handle a reversed BLF a6 Driver (Like lexel’s) on a DTP Board ?

Not sure, I guess it is safer to go for the 8x7135 version above without FET.
I started with 2000ma , Then 3000ma , Now FET
GREED :laughing:

In that case:go for it! :partying_face:
4715AS wont survive a FET, this is a IR LED with a forward voltage way below our white LEDs
2-3A on DTP should be possible, but FET would go >10A and boom
Black flats should work with FET

you could still cut one trace and do 2 thin wires to rewire PWM pins

A quick look on the datasheet mentions a Vf well above 3V, so this may be one of those 2xseries-die leds?
datasheet shows 3A at 3.8V this may work, but could still fry the tiny 1mm² emitter that has 9K/W thermal resistance
even our white XPL LEDs don’t like to be driven at much higher than double rated current

Has anyone received and put one of these together yet? Looking to use an osram flat black just wondering if anybody has done this combo with one of these boards yet
