All of the PcB designs that I've posted on this forum aren't going to mount under the Typhon like the one in the picture. That "Typhon/LDD combo" was a project that I built just for fun. I passed out 5 or 6 of them to other hobbyists and kept a couple for myself. I'll post the build files for that combo after I've finished tweeking it a bit. If you're interested in building one for yourself, just let me know and I'll have another run of PcB's made and send you a couple. The way I see it - "there's always a few people late to the party", so I tend to keep a few extra PcB's layin'round, just in case. LOL

Hey there, so i've received my 5x5 boards from iTEAD the other day. I ordered 1 black and 1 white; attached the zip file below and received 10 white and 10 black lol 
Can someone please tell me (based on attached zip) if i would need the LDD-700H or the LDD-700L on these boards? I am confused since the 700H is usually 10x5.
I would like to have the LEDs turn completely off when sending no PWM signal, and right now i don't have the 10k Pulldown resistors. Since the itead order wasn't so expensive i can order new ones if needed based on the outcome of the question.

I dont have a viewer to look at the fiels but the names of the files make it look like a 4xLDD-L board.

I crap.. i need to buy LDD-L for this (now i see using http://www.gerber-viewer.com/default.aspx). Can anybody tell me the difference?
And for the 700H or 700L how can i determine the max number of Leds? What info do i need for that?

Each 'product' you order from itead, is a set of 10 boards. I'm assuming they were around $9.90 per '1' you ordered? Maybe a little more because of the color. You definitely have the LDD-Lx4 5x5 v1.0. If you want to run the LDD-H you need the LDD-Hx4 boards. I posted v3.0 yesterday that has the pulldown resistors and jumpers to activate them.

I'm sure this has been asked before, but is the typhon led controller plug and play with these?
Yep- The Typhon is Arduino based, so it's compatible with the LDD's.

Gilles,
If your interested in selling 10 of those I would buy them. I was just getting ready to order some.

Yep.
I'm ready to order my boards rrasco v3.0 on itead studio
No ETA were listed per shipping method.
What's the turnaround on snail mail and UPS??
Spend the Extra$$ for UPS and get your order in 10 days.
FREE SHIPPING = This guy has your PcB's. Needless to say, You'd be waiting awhile. LOL

Excellent thread. I am an experienced programmer but not much of an electronics engineer, I am learning though. Instead of using the mean well drivers couldn't a single power supply be used and then a MOSFET for each LED channel?
Sorry if this has already been asked and answered.

LED's require a Constant Current to operate rather than a Constant Voltage - the Meanwell LDD drivers are a constant current driver.
In theory, yes. The Sainsmart is just another Arduino clone although there have been some documented 'quality control' issues.
Just thought I'd throw this out there since I know there are some that are chomping at the bit to get their build started...

has LDD-1000H's in stock. Ordered mine yesterday and they shipped this morning from California.
Happy building!
