Help with a Lexel 21mm driver and anduril

Flashlight Modding and DIY Parts

I’ve got a skillhunt h03 with a 21mm driver from lexel. it’s this one: http://www.metronixlaser.de/bilder/flashlight/21mm_driver_LX_v3.0.png
i’m having a hard time finding, well, pretty much any info about this driver. I’d love a schematic or circuit details.

Right now, I’m trying to figure out the button LED. in the picture, the LED connects to the L terminal. but my driver has no R1, R2, and the top pad is not bridged.

I’m kinda frustrated with how difficult it is to find info about this. what pin does anduril expect the button led to be connected to?

there are threads that have some useful info, but it’s like finding a needle in a haystack (even just looking through the massive first posts)

anyone have any ideas where I can find some of this info?

I added a 1k resistor to R1, that seems to work at least a little. the aux led gets 3mA and lights reasonably bright.

i am not sure what anduril version I have on this; I only seem to have high, flashing, and off aux light modes.

R1 and R2 is probably a voltage divider for reading Vbatt when the LDO is used (2S input), there are some jumpers near the LDO pins and they are probably there for bypassing it in 1S, then the voltage divider isn’t necessary (as long as the Vbatt is set as read from VCC in the firmware)

ah thanks. it definitely reads the voltage from the right place, though I’m not sure it’s reading it directly unless it offsets the diode drop when reading vcc.
