No, this uses the smaller version of the attiny13. Also the resistors and caps are 0603, some Nanjg drivers use 0805.
Oh yes, the smaller version was already mentioned. Thanks.
djozz, I spoke with Mouser today and was told they have offices in Munich and the UK, so you should be able to order the FET from Mouser there in Europe and not acquire the big shipping charges. As I recall, this should be just under a dollar apiece. Providing EU Mouser has them, of course. Digikey should be similar.
eu.mouser.com has them for .83Euro? Mouser-onderdeelnr.771-PSMN2R4-30MLDX
OK, so 13mm instead of 11mm? If we're going all the way up to 13mm, then I might space things out a little bit more so it's a little easier to assemble.
If you are expanding it to 13mm, do you think it would be possible to fit the 7135 on there also?
I have been studying wights 15mm driver single sided FET+7135 that is sandable to 14mm, he used the SSU of course, and if you use the LFPAK33+0603 smd components+ the attiny13a-mmu i hope it could fit 
The light i would like to use it in, is of course the Jexree Mini, for that it would have to be sandable to 12mm, and it would fit djozz Ultrafire LZZ-06 also.
Sorry djozz, i was wrong about the 11,6mm driver in the Jexree Mini, i must have mis calibrated my caliper, it is a 12mm driver.
One very nice thing about this MTN-12DD is that if & when RMM starts to sell these single sided 12mm fet drivers, those plus an XP-L on an 10mm sinkpad is a total drop in 
for the very nice 10440 host the 5$ Jexree Mini :bigsmile: Can you say ~1000 lumens at start from some very affordable parts 
Richard you really should considering selling that combo as a quick and relatively easy modded light in your store, there are not many 10440 hosts that can take a DD driven XP-L but this one can, and i bet you can sell a bundle of them and with a sane shortish turbo timer they should be quite safe even.
I think that what would be more feasible on a 12mm would be pads where you could air wire a 7135 if desired instead of having it mount on the actual board. There isn't room for it on the board.
Ok, good to know and thanks for checking out if it worked
But pads is almost as good :bigsmile: there is more room to add height than building up the spring side with components, because with something like with wight’s fet+7135 12mm driver it leaves less than 1mm in the tube with the spring fully compressed.
If you can do a 12mm or 13mm sandable to 12mm with pads for airwireing the 7135, please do
As far as i understand, if we don’t install the 7135 it should work just like the MTN-12DD.
Exactly. I never liked having any components or having to jumper over stuff on the battery side. I also didn't like the compromise of the attiny10/PIC versions, but the LFPAK33+attiny13a-MMU are an awesome combination for a tiny driver like this.
Yeah i agree, i felt slightly uneasy about components sticking down in the tube & out from the exposed driver when they would change battery, my plan from early on was to find a tiny light i could mod to very bright, & do it so safe i could gift it to family members and not worry they short something on exposed components for example.
And a single sided driver makes it much more foolproof and it will look stock, before you turn it on that is
I will still probably build one Jexree Mini version with a attiny13a-ssu, just so i can more easy test various firmware set ups to see what i really like in a twisty with that much power.
You might want to add this one to the OP. 
Over the past few months, I've been slowly working on an update to the original BLF SRK FET driver (design by Mattaus; development ideas from Comfychair and many others).
I present to you, the shiny new BLF SRK FET driver.

Done, I’ve refrained from adding your new buck driver but would be happy to do so.
Could this be filed down to fit into the Courui D01? According to this it has a driver diameter of 38.5mm. Here is a pic of the driver
Not really. This is 46mm. Why not use a smaller driver?
Like this for a SupFire M6:

Roche F6 or X3 DD driver with battery status leds
17mm board for Omten TS1273G1 12mm switch
Helios - That Roche F6 driver also seems to apply to the Roche AS31 as well. I got an AS31 and measured it out and seems to be a perfect fit, though the color LED's are not accomodated in the housing. Also the Roche F6 you can buy today seems to be under the Convoy label, and also has no holes for viewing the color LED's.
I built up one "Convoy" F6 already with this driver and it came out great! Problems were more with the host - the SS tail just cannot stay in. Also the F6 tailcap springs are uncoated steel - impervious to solder, so very difficult to wire bypass that spring.
Please provide the BLF thread links and parts list for the OP listing as well. I'm planning on building up a few more of these driver - Great Job by you and TK on this driver!!
I’ll add these after work this evening.
I just got what I thought was a nice email from Oshpark which I've copied some of it here.
Hi MrsDnf!
Your boards are being made as you read this!
We've sent the panel containing your boards to the fabricator. We expect to get them back around June 21st.
In case you're interested, there are 110 other orders on the panel along with yours, adding up to a total of 648 boards. Neat eh?
Order Details
Ordered on June 10th 2015.
Paid on June 10th 2015 via paypal.
Items PD68 Lighted Switch copy
0.80x0.80 inch (20.27x20.27 mm) 2 layer board.
The panel your boards are assigned to has been sent to the fab. We'll let you know as soon as they're back.
Thanks for the added projects Helios. I, for one, definitely appreciate the 20mm triple. A quad stencil for the larger 31-2 mm Noctogon boards would also be nice to go with all the EEX6 builds.
I like those emails… mine are coming back from fab on the 19th and the 25th, but they are 4 layer panels. I’ve noticed they sometimes have slightly different dates.
