Has anyone made an LED driver based on LM3463 6 channel driver IC?

hello @O2Surplus u can help me?
thanks

@ a crossroads - driver question

@ a crossroads - driver question

Not sure which way to go....looking for insight and suggestions.

So I have just about everything on hand to build 4 18" long makers heat sink led fixtures/modules. the intention is to be running 3 strings of 10 LED's on each heat sink, each string powered by its own ELN 6048D. 2 strings of CREE XT-E Royal Blues and 1 string of CREE XP-G Neutral Whites per heatsink. So a total of 12 ElN 6048D's.

But I have seen these meanwell LDD's and wonder if they are a better way to go?

Should I flip the ELN's? What type/size power supply should I be looking at for a project of this scope?

BTW: these will be lighting a 48" deep tank that is controlled by an apex. Also I did see and read about 02Surplus's nifty little apex to pwm controller.

Thanks for any insight gentlemen,

TR

Should you dump the ELNs and use LDDs with a separate power supply? Yep

Simple and probably quite a bit cheaper!

+1 the LDD are simpler and there are a number of different O2 designed boards on this thread and the LDD thread that work very well for diy.

48" deep,...what have you been lighting it with?---Rick

How do you guys upload a sketch to this board? Is there a quick guide or some pointers?

 

[007Bond]

Not sure what you asking. These boards are for driving power to your led's. You need some kind of controller to run them.

 

[vasko2grama]

I ment the o2 board with controller on board

You need a FTDI adapter between the Driver board and your USB cable. When programming the board using the Arduino programming software, go to the "tools" tab scroll down to "boards" <tools> <board> and select the "UNO" as the target.

I was using "pro or mini w ATmega328" and it didn't work... Tnx, using uno works like charm.

been out of action a while but starting to get better have we any code for this projet and a guide on uploading and connecting the screen and stuff
Many thanks

Simon-

Hopefully Tim will chime in- he's had a couple of the 5up A6211 boards for awhile now and may have some code that you would find useful. I know he was working on some code that would provide I2C communication between the boards. If not- I'll post some code for use with an I2C enabled 20X4 Lcd and a Dallas One wire temp sensor + 10 bit dimming on 2 channels.
You'll need a FTDI/USB adapter for programming purposes. You can find them dirt cheap on FleaBay.

many thanks i have one of the leads when i bough the boards just not been that well

Any Help is appreciated many thanks

Unfortunately my build has not progressed beyond playing with code snippets and designing. Had a brilliant offer for all the LEDs, but the supplier ran in to delay after delay trying to get some custom PCBs built with specific bins on board. He is now doing it all himself, so has ordered the LEDs direct from Cree and is putting them onto custom PCBs and stars himself, so should finally get my LEDs and be able to progress.

Quite happy to help with coding and have snippets to do most things, just no coherent program

Which screen are you thinking of? I use an I2C 2004 LCD (probably same one as O2Surplus'!) and it works fine and is well worth using for the extra screen estate compared with the 1602's!

[bigguyuk]

i have a couple but have that one TIM

 

[perkint]

Cool. To be fair, probably best starting a new build thread, rather than derailing this one a bit more

Tim

 

[bigguyuk]

that would be better

Hey Hey O2,
Trying to get in touch but the I am stuck with the 10 post before PMs rule.
Any chance you could possibly flick me an email: spam4neill at gmail dot com

Just bumped into this, it was a long but interesting read.
Quick question, does anybody have some PCBs that I could buy or the Gerber files needed to order them (assuming they are open source, ...)?

awesome build, looking use this as a starting point for my new light. O2, sent you a PM on the driver files. Also wondering if anyone has tested efficiency, or long term use on these little guys yet.

I'll get to your PM soon, just need a few minutes of free time first. I'll sneak this in though.... I've had my 5upA6211 drivers up and running 11 hours a day for over a year now, without a single failure. I recently upgraded my MeanWell power supply from a 48V/6.7 amp unit to a TDK/LAMDA 48V/22 amp unit and raised the driver's output to 1400ma on 12 channels. Still no failures. I'm not sure how their efficiency compares to a Meanwell LDD-H, but they're definitely more powerful and take more abuse. LOL :dance:
