I checked it my SC31Pro does not look the same as the reviews in BLF, as shown in the picture if it has all three pads on it.
It looks like these last ones with Anduril 2 if they have pad and the TS10 I have not received it but I have seen pictures and the pads are there too.
Here is a screenshot of my unit.
Drive SP31Pro Anduril 2
Edit:
Which firmware would you use?
In the list the most similar the Sofirn SP10Pro or SC36 t1616 there is not a specific one for SC31Pro.
Thanks.
If I am understanding this correctly, then the SC31Pro is running the same driver as SC36 t1616.
If nothing else, version check your light and see what it says.
Ok! Perfect.
Thanks.
Yes, it’s perfect, I like it.
Although I have a programmer I could order just the PCB but it is more comfortable this board!
I already wrote a PM to buy it.
I decided to compile a list of Anduril-based Sofirn/Wurkkos flashlights and the pin headers they use (Sofirn/Wurkkos can revise the boards use and even the “Anduril model ID” based on the chip they used, so there may likely be other revisions other than the one I’ve encountered.
Anduril version and pin header on Sofirn / Wurkkos flashlights
Sofirn SP10 Pro (1x 3-pin) {A2 '631'}
Sofirn SC21 Pro (1x 6-pin) {A1}
Sofirn SC31 Pro (1x 3-pin) {A2 '614'} [has other revisions like A2 '612' which doesn't have pin header]
Sofirn SC31T Pro (1x 3-pin) {A2 '615'}
Sofirn IF25A (no pin header) {A2 '612'} [may have other revisions]
Sofirn SP36 BLF (2x 4-pin) {A2 '612'} [may have other revisions]
Sofirn SP36 Pro (2x 4-pin) {A2 '612'} [may have other revisions]
BLF Q8 Anduril (no pin header) {A1}
Sofirn Q8 Pro (no pin header) {A2 '611'} [may have other revisions]
Astrolux EC06 (2x 4-pin) {A2 '611'}
Sofirn Q8 Plus (1x 3-pin) {A2 '614'}
Wurkkos TS10 (1x 3-pin) {A2 '614' and A2 '714'}
Wurkkos TS11 (1x 3-pin) {A2 '715'}
Wurkkos FC13 (1x 3-pin) {A2 '715'}
Wurkkos TS21 (no pin header) {A2 '612'}
Wurkkos TS25 (1x 3-pin) {A2 '715'} {earlier batch: A2 '614'}
Wurkkos TS30S (no pin header) {A1}
Wurkkos TS30S Pro (1x 3-pin) {A2 '715'}
BLF LT1-Mini (1x 3-pin) {A2 '621'}
BLF LT1 "A2/A4" (2x 4-pin) {A2 '621'} [has other earlier revisions]
BLF LT1 "A5" (1x 3-pin) {A2 '622'}
BLF LT1S Pro (1x 3-pin) {A2 '623'}
A1 = Anduril 1
A2 = Anduril 2
‘612’ ‘631’ ‘715’ etc = the model ID when using Anduril 2 version-check
(note: for the BLF LT1 lantern, there are many board revisions, from the Anduril 1 “rev4.3” and “rev5.0” boards, to the Anduril 2 with “Sofirn 1.0” marking and also “BLF-LT1-A2”, “BLF-LT1-A4”, “BLF-LT1-A5” board markings which may have different pinouts.)
I presume the 3-pin adapter means all use ATTiny1616 which are supported for flashing.
Much appreciated!!
Hi!
I’m also interested in buying one adapter.
Could you please clarify how I can do that?
Hi, i want a Flash Tool for my TS10. Somehow I can’t send you a direct message. Can you help me out. Thanks in advance.
PM sent.
Thank you @thefreeman for adding me. 
I’ve assembled and tested 30x USB-C to UPDI V2 adapters (designed by gchart, thank you!) in Australia.
There’s no light pointing down to illuminate the pads on this version.
For the record, my Wurkkos FC13 (running TK’s rev.727 from the multi-channel branch) blinks “0716” and not 715 at the start of the version sequence right after pressing 15C.
Ditto, “0714”.
So the SP36 Pro doesn’t have the 3 pin for 1616? Sofirn confirm the CPU is 1616
Sorry, my post was a question but I forgot “?”
ok, no prob and thanks for setting it straight.
But to answer your question: I don’t think so, the “into the head” pics I was able to find either showed no pads[1], or a very strange 4+4 (3+2?) arrangement[2] faintly resembling Hank’s.

I’m waiting for mine. After it arrived I do a pic
Please do and please tag me, the SP36 Pro is otherwise a perfect soda can light and I’d be very interested if there’s a new model or something with easily accessible flashing pads.
@dmenezes … so fast…
I don’t know if I can use @gchart pogo but I see it doesn’t do 3C to unlock for OFF so there is not the last @ToyKeeper recent branch and revision.
@thefreeman I can buy your driver and switch 
Probably 2.54mm pitch instead of 1.27, R for R, V for + and G for ground/-, you can solder wires from your adapter to the pads.
I still have 4 boards I could assemble, but it takes such a long time that it would be pricey.
I received this adapter and updated Sofirn LT1S Pro firmware (id=623) to the latest version.
Everything went smoothly.
@thefreeman, @ToyKeeper thanks for the flashing adapter and FW!
Those pins (also found on the Q8 plus, etc) are both too wide and in the wrong order for gchart’s adapter, but luckily I have a solution.
First off, you’ll need a rewirable UPDI adapter. I used this one: UPDI HV Programmer AVR Unbrick Unlock Microchip Atmel High Voltage Pulse | eBay (note that it uses the jtag2updi protocol instead of serialupdi like gchart’s). Make sure you remove the HVP jumper (read the description).
Now, get some dupont leads (e.g. Amazon.com ). Connect three to V+, V- and UPDI, then arrange the ends in the correct order (R = UPDI, V = V+, G = V-), and tape them together (I used kapton tape, but whatever you have to hand like masking tape or sellotape will work too).
Thanks to MG (great follow on hardware hacking and general cool stuff), 0.68mm pogo pins fit into Dupont connectors. I used P50-B1 - it might take a couple of tries, I think I broke 1 or 2 trying it, but once you get the hang of it they go right in. Congrats, you now have a Sofirn adapter that’s an almost perfect fit. Just triple check each time you use it you have the right orientation.
