1. wire up the programmer to the light

first speedbump

How do I connect programmer pins to flat driver pads?

anyone have a photo of the operation?

thanks

You would have to solder wires to the pads or create your own pogo adapter

thanks for the roadmap and info

How much is the driver size?
I would try upgrade on sc31pro host

The driver is 19mm, but I don’t see the point in swapping the driver when it can be flashed to Anduril 2.

the points are that Sc31pro driver haven’t regulated output, work with pwm and provide too much current for 3535 Leds at high modes. If I’m not wrong Sc21mini is regulated, no pwm and 1000lm max. Enought for lh351d or 519a powered by 18350 cell

I’m pretty sure the SC21 Pro driver is direct-drive as well. That small battery can’t provide a high enough current to damage the LED. Zeroair measured 2.5 A maximum.

@Sari33

Sc21mini is regulated

afaik, it is only the SP10 Pro driver that is sold separately.

IF you can buy the SC21 Pro driver (not SC21 Mini), I hope you try it and let us know if it works better for you.

@SammysHP

Zeroair measured

fwiw, that review is not for the Anduril version of the SC21…

[Verodin]

Very much looking forward to seeing the results of getting Anduril 2 running on these!

As for regulated/non-regulated output. here’s my output measurement of the pro using ceilingbounce in case you missed it: Sofirn SC21 mini - #161 by Verodin

[supreme]

Is this Anduril 2? If so, can someone ask Sofirn to reflash or use this going forward? anduril.2021-08-31.sofirn-sp36-t1616.hex

[SammysHP]

Why? That’s a pretty old version.

[supreme]

I haven’t kept up with Anduril firmware for all the various lights. Hence the if so part of my post.

Since it doesn’t seem to be Anduril 2, we will have to wait for someone to compile one. At least we know anduril.2021-08-31.sofirn-sp36-t1616.hex can be used to create an Anduril 2 firmware since Sofirn seemed to use their own version for this light

I think what SammysHP is trying to say is that Sofirn should be using anduril.2021-12-13.sofirn-sp36-t1616.hex since that is the latest official build of Anduril 2 that will work

[containerfan]

gChart, any chance that you could design a Programming Key for the SC21 Pro? If I understand correctly, it only needs three pins, but the key has to be five pins wide: (GND) (VCC) (blank) (blank) (UPDI). Too bad Sofirn didn’t put them together so that your UPDI key could be used.

I’m confused now

@Adair21

This entire time I’ve been trying anduril.2021-12-13.sofirn-sp36-t1616.hex and getting the slow ramping, but I just tried anduril.2021-08-31.sofirn-sp36-t1616.hex and it works!!

So it seems the latest Anduril 2 works but has problems?

Look at post #207. I improperly erased the MCU and that was causing some odd issues. The latest Anduril 2 build works great after I did a factory reset.

Who do we contact at Sofirn to see if Sofirn can use this build for future lights?

[SammysHP]

@supreme

Please no, there are more recent versions and Sofirn should talk to a dev (ToyKeeper) first.

Haven’t kept track of changes, but are there any fixes/additions that apply to the SC21 when using a newer version? If not it won’t matter using an older version.

Don’t recall if this was mentioned earlier; the TIRs Convoy/Simon sell for the S2+ also fit wonderfully in the SC21 without the glass lens and emitter gasket just as they do in the S2+. The head will screw down more for those who don’t need the warning label to line up

I grabbed a random beaded TIR from my stash, probably a 15deg, and honestly wish this were an option from factory, it’s great.

@DarkShot

Great info! Congrats and thanks

fwiw, I just tried it, and no go: (maybe cause dedomed)
