[Sale] 7. batch DD 1S/2S Bistro HD OTSM/NarsilM/Anduril drivers 12-47.5mm size S2+, C8, H03, MT03, Q8 Clicky or E-switch

The. 6. batch gets a little bit hard to follow for new people,
so I start 7. Batch here

Reflow now in oven, getting better results

Firmware:

Attiny25V running Bistro HD OTSM
OTSM works perfectly with lighted tail cap and hot light no more OTC timing issues
2S Bistro OTSM now on all sizes but 15mm available, 15mm 1S OTSM implemented with design change

or

Attiny85 running NarsilM v1.2 or Anduril
NarsilM manual, a lot of options to configure this one
NarsilM driver can be thermal calibrated as well
you can choose the temperature for step-down, but change it later in User Settings
the time for step-downs depends on the lights size/heat, a pocket rocket off a 14500 high drain will need a shorter time than a Convoy L6
standard will be 60°C
standard step-down time 45s

Information about this TA driver series here, notice that my drivers are developed further and have slightly different design

.

If you want fully assembled and tested drivers send me a PM

.

Available options:

there are different sizes available
15mm for 14500 lights
17mm for most Convoy, Eagle Eye, BLF A1 lights
17-19mm
20mm
21mm special for Skilhunt H03
20-22mm for various lights with this size
20.5mm Astrolux S42, 21mm thin board for Skilhunt H03
38.5mm Courui D01
42mm for Thrunite TN42 or 3 cell flashlights
46mm SRK, MT03
47.5mm Q8, MF01, MF02

2S boards are now available without the unreliable over driven AMCs in some sizes

- FET+0.3A output, by replacing the AMC with a small FET and resistors

  • 17mm as well FET+1A+0.15A with 2 different sets of low current resistor channels

.

This time will be using the Infineon BSC009NE2LS5IATMA1 as a high current low resistance MOSFET (1.25mOhm @3.2V)
You can choose a custom number of 7135 less than the maximum

Drivers will be fully tested

Springs:

for 17mm Board will be phosphor bronze in 2 lengths
for 15mm board the short spring fits (the long upside down but risky)
All drivers come without soldered springs, to stay below 10mm envelope thickness which is 2.2€ cheaper to ship

long spring for 20mm and larger
Or short spring

For 24-30mm boards those springs are good


I have now 0.35, 0.75, 1.0 mm² high flexible silicone wire for the drivers
0.75mm² max for 17mm drivers
0.1€ per inch
prices reduced to half of 4. batch as the shipping costs are relatively low for a bigger order

1.0mm² for 22 and 30mm drivers
0.175€ per inch

Prices:

15-22mm

12€ with temp+LVP calibration and max temperature preset,

per loose bronze spring add 0.25€
large steel spring 0.12€
springs can be soldered, but stiff long spring adds shipping
silicone cable can be added and soldered for 0.1-0.175€ per inch
also soldered short or large long spring plus soldered wires adds shipping cost

*also most high current new drivers got filtering for better LVP, but this makes re flashing impossible
there is a solder bridge you can open next to small C3*

Interested for my two AT40s. I’ve never bought on here before and I’m not sure how it works and I didn’t see a sticky about it.

I have a reverse clicky 14500 light that could use a new driver. Now it’s 1-mode on/off.

What options do you have on a 15mm board?

Is it a FET driven board or purely regulated? I don’t need Turbo mode, i need long runtime :slight_smile:

15mm is FET+4+1

Shipped today 4 orders

Could I get two 17mm drivers please, soldered wires and short spring please.

It seems I ran into a big problem

The latest drivers I built with new batch of AMCs get faulty

they do not shut down complete after the AMCs got first time used
more use and it seems more get faulty or one more bad

Those were ordered from LCSC, I build now 7 drivers in a row and all get faulty

Also very low moonlight levels do not work with them

Just hooked up a 22mm “D4” driver. It’s in the green one in the middle.

Anduril Runtimes at level 5/7 stepped ramp (should be running on the FET in the stock drivers)
The black D4 (stock driver - XP-G2): 3:15
The green D4 (LX 22mm FET+6+1 - 219C): 2:10
The silver D4 (stock driver - XP-L HI): 2:45

I know the 219C are inefficient, but the stock driver lasts an hour longer before stepping down.
Shouldn’t the FET+6+1 driver with the AMC’s last longer at high output?

If it lasts less long there is a simple reason it’s that it draws a higher current,
you can’t assume they draw same current as they have different ramping tables

Just took it apart. Looks like I also made a mistake. I only used 20AWG wire from the driver to the MCPCB :person_facepalming:

Lexel, do you produce any drivers in the 10440 size range - say, 10mm or 11mm? I don't see any listed below 15mm, so I assume not, but I thought I'd ask anyway.

12mm with 1mm copper rim

Hi. Sorry if is not the best way to ask. I am looking to drive 3 osram oslom luw with 15 volts. The driver could be square or round. I can glued with ceramic epoxy to a heatsink. I need 4. Thanks in advantage.

How do I go about ordering a driver board?

Interested in board for MF02, would it have to run standard battery config?

I have an extension tube on order.

I have the Buck that is 4S only with 12V LED

I know many have seen that I had huge delay in last 3 weeks literally came not to forum orders
I was barely getting enough time to deal with commercial stuff with Fireflies and Astrolux for example

last 2 days I was so busy completely rearranging my living room to fit a 190×70cm working table to get enough space to work more efficiently on flashlight stuff,
my couch, couch table, parts of the furniture and the cat tree were literally packed with flashlight stuff, also window and floor with a lot of stuff standing around everywhere

Also have at the moment 12 young cat babies that need to be dealt with to get them sold that eats time as they are now 9 and 10 weeks old from 2 cat moms
