Lexel has been “absent” for almost 2 weeks now.
Maybe it is better for you to send him a Personal Message to let him know about your request, so that he can see it when he returns!
Yes I got myself 3 weeks relatively internet free holidays
Hello,
Would the MF01 driver with dual buck be able to support tint ramping ?
I see no problem modding one Buck side to be on another channel for tint ramping
for moonlight and low levels there would be a shared PWM pin putting the Bucks synchronous into a lower output
the more challenge is to look into Andurils Tint ramp code to add the Buck PWM channel to the existing 2 channel tint mixing
So this would require hardware modification of your driver ? + anduril modification to support tint ramping. Would you be able to provide this to sell ? Or will I need to mod the firmware myself ? (Not sure I am capable, I am big noob in that regard).
Also this driver is only compatible with the mf01, not mf01s right ?, is this due to body difference (driver cavity depth ?), cell carier modability or something else ?
I don’t have the flashlight so I’m checking if this is viable to decide to buy it or not.
driver is quite easy removing one trace and wire it separately from the input resistor
looking at the lantern Anduril config file it seems it uses only one ramp register and rest is done with separate tint mixing code
so replacing that should be possible but has to be tested
Ok, I just ordered the mf01 so I’ll PM you when I received it, thanks.
Lexel, the 12mm drivers are populated single sided or double sided?
Also, they work with both Anduril and Bistro UI?
Thanks in advance!
bottom side has a cap and 2 resistors but it plays no role if used with a spring or button
Lexel, what is the MOSFET in 12mm drivers?
Thanks for your reply Lexel!
If it works, I will use the driver in a sort of “piggy back” way, incorporated in the structure of this driver:
It will be connected to the PCB and to the switch it has there. For your explanation, could I use it without those 3 pieces on the bottom side in this configuration? I am concerned about the small space I have to fit the driver on that hole…

Nexperia PSMN2R4
AMCs are even thicker than those components, if you are concerned about total battery length then use no button and solder just a wire in the hole
I see, thx for the info.

Hey Lexel, i made payment 23rd May and last mth 16 Jun you said you should have them out soon. It’s been another month, and been messaging you past 2 weeks with no reply. Can you let me know what is going on?
Lexel,
I want to upgrade my L6. Will your 30mm buck driver work with 3 LifePO4 batteries (9.9V)? Additionally, is it current regulated? Can it be pushed to 9 amps?
I wonder if anyone can help me identify two Lexel drivers.
I ordered one for a ThruNite TN42 and one for a ThruNite TN40S, and I’ve managed to get them mixed up. 
My TN42 is a single XHP35 HI emitter. My TN40S is four X-PL HI emitters.
I ordered these drivers several months apart, and they are slightly different in physical layout. They each have some unpopulated components.
I am not very knowledgeable in driver design. One obvious difference I can see is the values of resistors 8, 9, 10, and 11 on the non-spring sides. Perhaps that’s an easy clue?
I am currently out of town and have no DMM, clamp meter, or power supply. Can anyone tell which is which solely by physical differences?

What differences are you seeing?
IDK, you might need Lexel to answer.
Are they both 12v boost drivers?
Probably Buck drivers.
