Meanwell LDD driver: for those who want to dim to 0 using Arduino

O2 those socket headers are the ones i was planning on using on my nutshell board
the only way to pull off the duel space design

Oooooh I see what you did there. Did you know that you can use the "Mirror" command and set components on the bottom side of the PcB? Using the combination of offset between components and the "machined pin headers" would allow you to mount the LDD-H and an SCW at the same time, rather than "one or the other".

LOL. I'm going to have to create a double sided 10cm X 10cm "16up LDD-H Pcb" just to keep up with you!
 
that's the best advice i got all year
No you won't have to keep up i will never get done i keep changing my mind besides your the master

Thanks O2, didn't see that about Mouser.. sorry.. :(


LOL- No worries. I've done the same thing more than a few times. I have to laugh whenever I see s company advertise a product that they don't actually have in stock. I equate that to a new car dealership advertising "New 2016 Models" a full two years before the cars go into production. What's the point of advertising something you can't sell yet?:rollface:
 
ok so i figured out how the mirror command works
thanks O2

LOL, That command comes in handy as you can effectively "double" the amount of PcB "Real Estate" available on the PcB. Just be aware that "through hole" components won't present any challenge, but SMD components will require some prior planning when it comes time to actually soldering them to the board. Meaning- some of your previously soldered smd components could fall off the PcB, if you overheat the opposite side during the soldering process. I learned that lesson the hard way. LOL
 
O2,

Can I use your 8 up pcb with any pwm signal? I'm thinking of using it to drive a couple of multi-chips to control the separate channels.. Any suggestions?

I'm not sure what you mean by "any pwm signal". The PcB's in this thread are designed for use with the Meanwell LDD-H. The LDD-H requires a 5V PWM signal for dimming. You could use any of the available Arduino based controllers or similar, as long as it's a 5V PWM signal.
 
The "Elves" have been busy again!

Just built out a new 8up PcB and a new 4up LDD-H that includes an SCW12 DC/DC convertor and an arduino PWM fan control circuit. Check em out. I'll post the build files if there's an interest.

If these are the same width as the boards with just four LDD, then yes, please. :)

The 8up measures 100mm wide x100mm tall and the 4up 100mm wide x 90mm tall. The new 4upLDD-H/SCW has just been "stretched vertically" to accommodate the SCW convertor. It's the same width as my previous 4up LDD-H design.
I'll post the build files for both PcB's soon.
 
Hey O2,...Happy Thanksgiving! Question for you. On the 5up board you were working on for me, is the general layout set, other than the resistor sizes? I know you had said that you ordered some boards with a larger pad for the 6211's. What I wanted to know is could I order the boards now with the files you sent me and adjust the part sizes as needed? Thanks,---RICK

Hey Rick! Happy Thanks giving! The Component "packages" have been set on your board design. It's the component "values" that may need to be adjusted. Since that board has been designed with your preferred connections in place, I'd say go ahead and order a batch. We can always adjust the component values later. I'm actually thinking of sending you a fully built out copy of my 5up A6211 PcB design, or 5 of my little A6211/LDD-H drivers so you can put them to test with a real dream chip. WHAT SAY YE PILGRIM?
 
Wow O2 , What a generous offer! I don't have my DC's yet. I'm going to have 4 total on my build.
I want to build the board and play with it on my Jarduino before I hook it up to a DC. If I mess up one of those guys, its a lot of $$$ down the drain. I figure if I lose a couple of 10 watters no big deal. I'd like to build a mock up with the cat5 connectors and get the Jarduino to control it before I buy the expensive led. I usually mess up at least once when I'm trying something new.LOL:lmao:Thank You---Rick
 
Can the A6211 be used to drive a 50W multi chip I will be using 6 of them 34V at 1400 ma is better than 1000 ma I would be happy to test a few for you

Sweet, so they'll still fit in the top slot of the Makers heatsink. Thanks, you're a badass and a half!
