This is a great driver, all I use anymore for 17mm 7135 drivers!
I run BLF A6 and bistro FW but it would be just fine on biscotti, if loosing that last 350mA concerns you just bridge MCU pins 5 and 6 (after programming).
:person_facepalming: Why didn’t I think about it…
Edit drivers are tested and running in multiple lights. They work great
Couple new FET+1 drivers I’ve shared:
21mm on board e-switch and 5mm AUX LED
designed specifically for an ultrafire AT-008 but if you leave off the switch and 5mm LED its a standard size (actually the switch placement should work in several other lights too, just the 5mm LED is unique)
“17mm FET+1 v2 (first version rendered right but wernt fabbed right, that’s fixed now) 
Probably even less use for this one since it uses a switch daughter board but again, if you wire your own switch it is a standard size.
Both use the GT_Mini target for building FW (the 17mm Sc02 can also use the D4 target since it doesn’t have an AUX LED).
only here is under one AMC, would you give advice so that you can handle up to 8 AMC? as it is in convoy s2/s2+
Maybe is emisar d1 driver somwhere?
Big Thanks to ” Cereal_killer”:http://budgetlightforum.com/user/8679 !
Helped me with 29mm and 30mm contact boards.
Original quote from here:
Thank you Rufusbduck for this thread. I’ve been looking for 10mm drivers and it let me found notably more than I thought was available. 
Pretty old thread, but used to be quite active and was the central main thread for our BLF drivers. Lots of famous names here...
Yep. Couldn’t agree more Tom E.
Interesting thread. Does anyone know where I can find boards for lighted side switches on Oshpark?
Perfect, thank you Chatika vas Paus. Those are the ones I have been looking for. 
FET+1 D4 layout with indicator led support on Pin3. Anduril compatible!
15mm
Been looking this over but can't see pin #2 connected to a pad for the switch - did you run out of space for it?
I know there's not much room on a 15 mm, to say the least.
DEL has a good write up on his 17 mm FET+1 here. He writes these are the mandatory parts:
- C1 10 uF
- D1 diode
- R3 100K ohm to eliminate unintentional flashing during mode changes
- R5 4.7 ohm to eliminate unintentional Vcc boosting during PWM
C2 and the R4 47K ohm resistors can be eliminated
Right, no space for pad , just connect straight to pin. Why not? 
For 15mm, we make compromises
Might make it a pain to re-flash later
Sure, I've done it before.
I tried to (quick) read the entire post to find FW3A switch board or contact board but couldn’t find any.
Is it still a rare part?
Nice! I'm attempting to order from PCBWay - $5 + $8 e-packet shipping for qty 5, total $13. Decent price, no rush.
Looks like PCBWay has to do an approval on the order first. Thinking they will take PP. They also offer a ton of options - hoping the defaults are good for us.
