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

Thanks O2,...I'll ck it out. Reason I asked, was I have another RTC from ebay, and I thought I was going to just pull the batt from it, but its to big. The 12mm sounds right, because the holder measures 1/2".---Rick
 
Oh, and by the way,...hope you have another slow day at work O2,...can not wait to see your next board idea. lol---Rick
 
it is a 3v. back at work and had a look at the rtc battery. as 02 said it is not important to run the rtc, its there if the power goes out it will keep correct time till you power the arduino board.
 
Got it,...Thanks, after I thought about it, I didn't think 12v for a rtc., ya, just so it don't lose its memory if power goes out.
 
Lookin' good Rick. It always feels like "Christmas" when new PcB's arrive. LOL It's too bad the A6211's are still a way off yet.

I've got 5 different PcB designs being made for me at SeedStudios, right now. I went "all in" with the idea that I'd save some money on shipping, but got a surprise instead. It seems that shipping gets a lot more expensive when you exceed the arbitrary weight limit. LOL I gotta pay $82 for 8.5Lbs of PcB's. At least I'll be flush for awhile LOL. I panelized my little A6211 driver, so that 8 of them will fit into a 10cmx10cm PcB. I ordered "20" LOL, but once I cut them down to size - I'll have 160! Plenty to share!
 
Ya those boards are dead weight lol. I rechecked Digi on the 6211 back order,...I think they backed them up to feb 10-11? there about. I thought they had them listed around the 2nd. What date did you have them down for? My little copper heatsinks should be here first of the week also. Funny, I paid for them in Canada and they ship from China. You see the pads on the back side of the boards for them,:thumbsup: I'm really getting anxious,...now I need to get the rest of things on my shopping list lined up.lol:bounce1: Thanks again O2---Rick
 
lol there is at least 2 foot on the ground and 2 foot more has melted off in the last few days I would love 78 hell I would love any thing past freezing tired of ice and snow
 
Well- I managed to scrape up enough A6211 chips to build 1 copy of my latest 5up design for testing purposes. Below is a photo of her. This version has an Atmega328 and a DS1307 slapped on the back, and also features connections for a Dallas temp sensor. The drivers can be controlled either by an external controller (think StormX)or by the on Board Atmega328. I added script to the bottom of the board that describes the Arduino pin assignments used by the on board chip for PWM control, Cooling Fan control, and Dallas Temp. I also doubled up the I2C and Dallas One Wire connections to add the ability to "Daisy chain" a number of these board together. Soldering this thing together was not fun. LOL Let me know what you guys think?

All wee need now is a source for cheap custom heatsinks that these would have a slot for and space for LEDs, think board in center, LEDs on both sides.

LoL- It fits the top slot on Makers Heat sink out where the cooling fan resides. I've got a 6 footer and the plan is to mount 5 driver PcB next to/ between the 6 cooling fans. I can't think of any cleaner way of doing it.
