[Sale] BLF GT Driver for Astrolux MF02, Thunite TN42, Niwalker BK-FA30S

A Narsil buck driver designed on the BLF GT circuitry to fit the MF02
Will be set up for 4S battery configuration for the 12V LEDs, can run XHP50 and 70 up to 6A, equal to 12A @6V

The price for the driver is 22$ or 18.33€

XHP50/70 above 5A needs upgraded parts 2$

4$
shipping worldwide from Germany with priority air mail
optional tracking with 25€ loss compensation adds 3$

The driver for MF02 XHP35 LED is 2.5A same as the GT, same UI
for XHP50/70 can be higher current

I am discussing with DEL the needed changes
So far Buck frequency changed from 800 to 500kHz
input and output caps doubled, the design already has pads to fit 2 caps instead one
Diode 3A to 5A
inductor from 6A to 15.5A

6-8A should be no problem to get to

The battery carrier needs to be modified to 4S its pretty easy
2 trace cut and add one bridge
I will check the battery carrier tomorrow and may also add designs for modified boards on Oshpark

XHP35, 50 and 70 will work well
for XHP50 and 70 a Star with the thermal pad not connecting the 2 LED pads over the thermal pad is mandatory
so for 12V reroute over a separate trace would be needed

Those Sinkpads are OK, MTN, Fasttech and LEDDNA sells em

This LED star will not work if the star is not insulated from the body

TN42

Niwalker BK-FA30S

added 3 pads for the auxillary switches,
one providing 5V for the Turbo switch
one sets multiples the current by 10 or goes to Turbo
the other divides the current by 10

HaikeLite MT07S design finished

Interested. But I have no technical expertise in modding anything, not even a cucumber, much less a flashlight, will you offer your services, to those who need help?

I bet there is someone near you who can help with the driver change and battery carrier mod
I am from Germany so shipping costs would kill it

I’d be interested in a couple. Are you planning different options with it in respect to current and output voltages?

My current and or voltage measurements are only relevent to anything that I measure.

I will build those with 4 shunt pads

The standard BLF Buck from del has a 0.091 shunt
I will be using 3 0.33 and one 1 Ohm resistor —>0.091 Ohms
Of course it is possible to go to different values for different output currents

The inductor is rated 6A, so that’s a current that should be without any problems availiable

Hi! Sorry I am not expert in MOD but I would like to know what do you expect with this Driver in the Astrolux MF02? I am going to buy a MF02.
Thanks.

This driver has the awesome Firmware Narsil

Battery carrier needs 2 traces cut and one bridge soldered to go to 4S/1P
Driver will be same size as MF02, so basically solder wires from one driver to the other

Hi Lexel. I have not done my first mod yet but I am interested and this does not seem like it would be too complicated. Would you let me know what you think this might do for the MF02, how it might affect performance of the light? Thank you

Not too complicated the Battery carrier and driver replacement
The LED will be driven as hard as in the BLF GT and you got a great Firmware with NarsilM, highly customable

you have to ask DEL if that’s possible its his driver circuit

This driver is for 12V LEDs, SBT-70 is a 3V one and wont work with the current it needs

XHP35, 50 and 70 will work well
for XHP50 and 70 a Star with the thermal pad not connecting the 2 LED pads over the thermal pad is mandatory
so for 12V reroute over a separate trace would be needed

I think I can live with this

the question is if a 8.5mm high inductor fits the head or if I have to take a smaller one

P.S.
Design got improved
MF02 measured 8.3mm for parts height so the 7.5mm inductor will fit

OP changed to sale topic

Price is 22$ plus shipping

PM sent to all that replied in this topic

parts and boards for 30 drivers ordered
(10% extra parts for tests and maybe 3 boards from Oshpark)

I also added the 2×2 LED boards to the Seed order,
so if you like different colors or just more even lighted switch you can take one as well
I got SMD LEDs in different colors
CW, NW, green, emerald green, yellow, orange, red, blue, ice blue and pink

Hi Lexel. I guess you received my payment for two drivers, just cant see my name on your spread sheet. I slipped you a couple of dollars extra so all should be good here. Beer
