Well, it's $2.50 per board at a package of 10. As it stands, I am creating the files, but it's up to everyone to get the boards printed. If someone wants to buy a handful and distribute them, that's fine with me, but as of now I'm just creating the boards.
Let me make a few and see what I can do. Keep in mind you'll have to use the right terminals or they won't fit. I normally have to build those parts too.
BTW, thanks for the LDD library, saved me a some time.

Okay....
Looks like a 5x5 board fits 4 drivers well. If I really tried I could probably fit six, but it wouldn't be pretty. I wanted to start with this and I can make variations of this one fairly easy.
Manufacturer part numbers for Phoenix connectors:
2 pos - 1751248 (linky)
4 pos - 1751264 (linky)
8 pos - 1751303 (linky)

Could J1 and J2 be combined so a guy would only need to buy one type of connector(2-8's), or an 8 and a 6?

I'd be interested in couple boards, they'd certainly look a lit nicer than the proto boards I have now.
I did just notice a flaw in this whole idea. I was thinking that 8 drivers might fit nicely on a 10x10 board and was shocked to read that 4 would fit on a 5x5. Then I clicked on the image and learned something new. LDD-H drivers have an entirely different pin layout and are much larger than than LDD-L's.
EDIT: would it be wise to an extra Vin- terminal to accomodate the PWM-?

Combining them into an 8 would facilitate adding an extra Vin- or two.

oh yea I just noticed that... we need that layup with LDD-H's (those are what I use)
I also like the 8 pin strip ideas, because if you do 2 vin and 2 vout it makes daisy chaining boards easier
LDD-H's use a total of 9 pins... they have 2 vin+ 2vin- pwm dim 2 vout+ and 2 vout-

No, they would laugh at you. You have to send gerber files to the board house. Once the layouts are finalized, I can provide those.
Yes. I thought about using a 6 pos to begin with, but thought it would be easier to identify the ports this way. Easy to modify if we want.
I used LDD-Ls on a previous fixture, which is why I chose those. I wasn't aware anyone was using the LDD-Hs.
I don't follow. Why would I need to add a Vin-? I think he just wants a single 6 pos instead of a 2 and a 4. Less parts. If an 8 was used for some reason, the terminals could be left unused.
Well, the driver and controller need to share a ground, so that might not be a bad idea. I didn't think of that when I threw this together, of course, I would probably ground the controller to the supply GND anyways. Ground is a ground. Usually.

I'll take a look at the data sheet, but why does it have those extra pins? What added benefit do they provide?
LDD-H's can be ran up to 56v input compared to 36v input of the LDD-L, but as for the additional pins I really don't have a clue.
the H's are just more flexible overall though, the additional voltage allows them to run more LED's per string as well too, plus you can get an LDD-H in 1000ma

This is a 10x5. I believe itead lets you go up to 10x10 for the larger boards. This board would cost the same as a 10x10. I could probably double this up and put 8 drivers on a 10x10, but I don't know how useful that is to people. Like I said, I'll just make a bunch and whoever want to use what, go for it.

rrasco if you were anywhere near me I'd totally get you something really special.. like a cupcake or a pack of twizzlers
LOL...
What drivers were you wanting to use? LDD-D or LDD-H? I can make a board with 8 drivers if you need one.

22 bucks plus shipping for 10 of those 5 x 10 boards.. I don't think I could buy everything to make a few boards at home that cheap lol

For six LDD-H, you're going to need at least a 10x10 board. I can make the layout for you if that's what you need.
I didn't even know they offered those sizes or color options. I'm so used to going to the istore before the imall was there. Even though my last order I placed through the istore. I'm distracted easily.
