Put your Oshpark driver projects in this thread and I will organize them here in the op.

I would like to put all of the relevant Oshpark projects here as it can take some doing to locate them otherwise but will refrain from snatching them without the approval of their creators. Posting a link here will be considered as tacit approval and I will endeavor to keep this op updated.

This thread is for the listing of open sourced DIY projects that are listed on Oshpark not for pirating existing work. I’ll do my best to prevent that sort of abuse but will need your cooperation, thanks.

I’ll include stencil info where available.

Stencils:

Triple Cree XP for 20mm
Noctogon boards by Helios.

Cree XM and XP solder paste stencil by Helios.

3 x XP Cree(+1) 32 mm Noctogon by Helios.

Cree solder paste stencil for MTG, XRE, XML, XPG/Nichia by Texaspyro along with

Directions for ordering from Oshstencils.com. These instructions can be used to acquire a stencil for any of the projects listed below. Not the case at this time but hopefully it will be soon.

Mtnelectronics has some of these as boards or mod kits on his PCB’s - Mod Kits page. And will soon have more. if you buy them along with other items you will end up ahead of the Oshpark prices.

FET based drivers: These were generated in part through pm’s but the ongoing development for the next four boards is in this one. Links to parent threads will be added as soon as I remember them.

Roche F6, X3 DD driver with battery status LEDs. By Helios

MTN-10DD 10mm linear DD FET driver uses Attiny mmu and LFPAK 33 FET. Use the mmu breakout board above for programming before soldering to driver board. By RMM

MTN-12DD same as MTN-10DD but 12mm board. By RMM

The BLFTiny10DD, BLFTiny12DD, and BLF15DD all use the same irlm2502 FET for it’s small size but otherwise are similar to the larger DD drivers which use the vishay 70N 02 FET. The 10DD AND 12DD are too small to have a center positive spring pad and require a separate contact plate.

The following larger FET boards were developed using the Vishay 70N02 FET which is apparently available but no longer in production. The “similar single FET” has been tested and now works with the new location for the input capacitor.

Good idea this thread :slight_smile:

Duplicated information.

5

Sorry Matt, I just used the Oshpark titles.

6

Oh no worries I didn't see your edit. Your post is better :)

7

Maybe?

8

Hey, there's a 15mm driver too, very interesting, what's the story?

What I think that I see is no minus-ring on the battery-side (same as the 17mm and 20mm version), and no space on the board for the FET (that makes sense because it would never fit).

Nice work Guys, Thank You very much for sharing!

11

Different FET on the 15mm board. I need to update the descriptions a bit better. I rushed putting them up this morning.

Lack of GND ring on the reverse sides is a cock up. Will be corrected later as well.

12

Also diodes are probably not BAT54’s… those are in a 3-pin package. I usually use BAT54’s since a) I have a few thousand of them b) if you buy the right version, you don’t put them in backwards c) they are easier to hand solder than some of those tiny buggers. In a pinch, you can usually slip a 2 pin diode onto the BAT54 footprint…

13

Hello Mattaus!

congratulations for your PCB!

What do you use to draw them?

I'm downloading Kicad, to try to play a little!

What do you advise me to start?

thank you!

14

I see, I looked up that little FET (0.37 euro at a local website, I bet it can be had cheaper), it has an internal resistance of 0.045 ohm, that would give a voltage drop of 0.1V at 2A (if I remember Ohm's law well ;-) ).

15

Use CADSoft Eagle. Its free. Any tutorial will have you on your way very quickly and then its just a matter of practice, practice, practice.

16

I’ll put them up if it’s ok with TiVo. Don’t want anyone left out but also don’t want to step on any toes.

17

Sorry Matt, I was rushing a bit this morning myself and didn’t look them over before copying the links from Oshpark. I’ll mark them in the op as not ready for prime time until they are.

18

OK I've changed the 15, 17 and 20 Direct Drive drivers. You'll need new links though. They are all under my OSHPark profile.

19

The diodes on the FET boards are the stock off the Nanjg boards, I had to special order the ones you have on your 20mm I built TexasPyro…but it worked like a charm though
(DIY’ers can’t be choosers :wink: )

It was my fault the 17mm board got pushed…we hadn’t reviewed it…my apologies to you Mattaus. I already ordered 3x of em…so that is my penance for rushing you.

20

So that last SRK board with the FET looks rather awesome. I just can't keep up with all that is going on in the world of drivers. I'll just wait until RMM stocks them :)
